ABOUT ME
Who Is Brian Makau?
Brian Makau is a Junior Developer on a journey to be among the best developers of his time. Like many other people I started out life from a very humble beginning, but that's no reason to hold me back from achieving the absolute best that I could.
My Story
I started out life as a smart kid. Not to toot my horn or anything but from a young age my friends, parents and teachers told me I had aptitude and was able to achieve great things. Unfortunately life was not that easy growing up. I came up in a very hostile home. Life always threw obstacles at me but I was and still am a fighter, so everything tossed my way, I was able to combat. I tried real hard and lucky enough I'm where I am today. The loss of my only parent was one of the hardest things to ever happen to me because she was my whole support system. I do not say all this to seek pity, but rather to show everyone that even they can make it if they're determined.
My Education
My education is the most important part of my life. School was like an escape to me when I was young and I got adapted quite fast. I was a gifted student in primary school and even in high school I maintained the consistency. I graduated primary school in 2012 and perfomed fairly well. I enrolled to Mumbuni Boys' High School where I graduated from in 2016 and scored a B(plain) grade. After that I enrolled in Mount Kenya university to pursue a Bachelor Degree in Energy and Environmental Engineering. I finished this in 2020 and am now a proud student of Moringa School under the Access program.
Why Programming?
I decided to do programming out of curiosity and passion to know how to code. I really enjoyed the company of my developer friends and I always wanted to be involved in what I saw them do. I did not hesitate to apply to Moringa School when I got the opportunity and luckily I made it. Coding is one of the things that makes me extremely happy. I enjoy the thrill it gives me and the challenge it poses. The idea that I cannot learn all there is about coding is amazing. To get to meet with different people, to learn from them and to maybe teach them a thing or two is purely amazing. I couldn't ask for anything else!
Hobbies and Interests
- Cycling- Cycling is one of the things I have loved from a young age. I did not have a bicycle of my own growing up but improvised a lot and found ways to enjoy riding bikes as much as I do.
- Swimming- Swimming is a sport as much as leisure to me.  I also enjoy the weekly sessions I have for practice as well. It serves both of my want quite okay.
- Travelling- Part of the reason I chose coding is that I want to travel a lot, and I know coding will allow me this. I enjoy going to new places every now and then. Enjoying new environments and getting to learn different cultures and traditions of different places. It will allow me to see new sites and appreciate what I have and don't.

Sonny Bill Williams signing shows Toronto Wolfpack's global ambition is on right track
Unveiling of former All Black Williams is bringing dream closer for Toronto owner Eric Perez in bid to give rugby league worldwide appeal
by Nigel Wiskar, https://www.mirror.co.uk/authors/nigel-wiskar/Sonny Bill Williams was presented to the world's media at Arsenal's Emirates Stadium on Thursday.
The former All Black and New Zealand heavyweight boxing champion is returning to rugby league with Toronto Wolfpack.
Our man Nigel Wiskar was there to take in the scene.
The banners attached to the middle tier of the Emirates Stadium give an indication to the global nature of the Premier League.
They come from far and wide and run all the way around the pitch. Arsenal Kenya, Seychelles Gunners, Arsenal Singapore, Maltese Gunners are all up there, the traditional red and white colour scheme broken by a rather garish green and gold Arsenal Australia effort.
You can see them from the balcony attached to the Woolwich Suite of the club where over 50 press and broadcasters have gathered to see Sonny Bill Williams officially unveiled as a Toronto Wolfpack signing.
He’s not a global brand yet but over the course of the next two hours you would think so, such is the attention this large, softly spoken man commands.
 Not quite all black then and now no longer an All Black either.
He is flanked by Wolfpack CEO Bob Hunter to his right and head coach Brian McDermott on his left.
Hunter wears a permanent grin, like a man who’s won the UK Lottery and its Ontario counterpart on the same day.
McDermott, as ever, is more reserved but speaks thoughtfully and intelligently about the prize cargo coming to town.
He admits he “verbally machine-gunned” Williams when the pair sat down for a 45-minute chat which morphed into two hours, soon after England had beaten New Zealand in the semi-final of the union World Cup.
McDermott says it was one of the best games of rugby he had seen with the room breaking into laughter when Williams gently shakes his head.
“I’m normally a funny man. I don’t know why you’re laughing,” says McDermott before he realises what has happened.
There is mention of the buzz word ‘brand’, a word that will resurface throughout the afternoon, a word more associated with the likes of David Beckham (or Bickham as one of the Kiwi journalists says).
And then the nitty gritty. No hype and bravado and quick sell over his stellar signing, just the straight pragmatism we’ve come to expect from McDermott.
“I see him making a mark in the final third of the year, not from round one. There is a transition from union,” he says.
That's not quite on-message but it shows who is boss at the club.
More chat about “a billion eyes” on that rugby union game and on the "product".
At this point it’s easy to forget we are hear to talk about Williams’ considerable skills on a piece of turf, artificial or not.
Finally Williams gets to speak. He’s quizzed by reporters from Australia and New Zealand before the man from the BBC gets a question in.
He undoubtedly has a presence and when he’s next placed in front of a Wolfpack backdrop for TV interviews, the bright lights frame his considerable features like a film star.
He finally sits at a circular table for time with the reporters from the UK, shaking mine and everyone else's hand one by one and displaying the charm his CEO will be hoping is translated into shirts off the rack, bums on seats and clicks on sites.
He discusses his Muslim faith, his family and his belief he can have a genuine impact on kids in North America.
This is a man brought up in a home with no wallpaper but he admits to us he trained twice a day at the ages of 13 and 14 so he could get on TV and buy his mum a home.
And then he’s away. More interviews, more appointments. Life is busy when you’re a brand.
Five years ago I sat in a cafe called School opposite Wolfpack’s Lamport Stadium having breakfast with Eric Perez.
We talked about Toronto, about Iron Maiden and about his dream to form a rugby league club that would play in that stadium.
The table of three young women next to us giggled through their brunch.
“I want them coming to our games too,” he whispered. “We want everyone to come and enjoy the greatest game.”
I caught the tram later from the north side of the ground back into the city wondering whether I was speaking to a genius or a lunatic.
Seeing Sonny Bill Williams at Arsenal with the flashbulbs going off and everybody wanting a little piece of him would suggest Perez is a genius.
On the wall on the opposite side of the Woolwich Suite from Arsenal's pitch is a saying from legendary manager Herbert Chapman in 1925.
It reads: “I am going to make this club the greatest in the world.”
It sounds like something Perez would say.
You suspect Sonny Bill is too modest to utter those words but watch this space. Anything is possible.

+++ title = "Antwerp" lat = 51.217206 lon = 4.395904 +++
Antwerp is the principal city of Flanders — i.e. Dutch-speaking northern Belgium — and today, its rich historical roots and its lively bar scene attract many a tourist or two. I didn't stay any nights in Antwerp; but I spent most of the day here today, on a trip from Turnhout with my friends Annick and Stef.


The lady identified as Lydia Roberts, 21, felt “violated” and “disgusted” after finding the sick images on a second phone belonging to Adam Wells while he was at work.
But she discovered pornographic images of children from a Russian website on his spare phone when he left it at home in July 2017.
In a heartbreaking text to her best friend, Lydia said: “I’ve been living with a paedo”.
She confronted Wells, 27, by text and reported him to police before feeling so “ashamed” that she hanged herself at their home hours later.
Wells was slapped with a 12-month community order after admitting possessing 31 indecent photographs of children and was ordered to sign the Sex Offender Register for five years, complete 150 hours unpaid work and pay a £85 victim surcharge.
In an interview with the Mirror UK, Lydia’s devastated mum, Michelle, says she holds “vile” Wells personally responsible for her daughter’s death.
Wells had found Lydia dead at 3.30 in the morning when he returned home from a night out with friends and colleagues.
He subsequently appeared at Manchester magistrates court in July 2018 were he admitted possessing 31 indecent photographs of children and was given a 12-month community order.
He was also ordered to sign the Sex Offender Register for five years, complete 150 hours of unpaid work and pay a £85 victim surcharge.
Lydia’s mother Michelle has since spoken out about how she holds Wells fully accountable for her daughter’s death.

Display licenses, full-text links and ORCIDs for Crossref DOIs.*
Generate a DOI popup for your own DOIs. Try it out with the form below:
The DOI popup is a jQuery plugin compatible with Bootstrap. In fact, the plugin extends Bootstrap's
tooltip.js
, so if you don't currently include Bootstrap in your site, you will need to include tooltip.js
and some CSS. If you want to style the popup yourself, you can exclude the premade CSS.
Required bits:
tooltip.js
. Include this if you don't have the Bootstrap javascript.doipopup.js
. Javascript for the popup plugin itself.doipopup.css
if you want the plugin
to look like it does on this site.img
directory. Put these wherever you like - their location
can be specified as an option.Now you can create the popup, passing in a DOI:
$('#my-doi-popup-button').doiPopup({doi: '10.5555/12345678'});
Alternatively, when no DOI is passed, the popup will attempt to look up a DOI from
any available dc.identifier
meta tag on the page:
$('#my-doi-popup-button').doiPopup();
The plugin's behaviour can be customised by passing additional options to the doiPopup
method. For example, set a custom image path, and custom content type labels:
$('#my-doi-popup-buttom').doiPopup({ imageLocation: '//cdn.mydomain.com/doipopup/img', contentTypeLabels: {'application/vnd.me.custom-xml+xml': 'Custom XML'} });
| Option | Type | Description |
|---|---|---|
| doi | String | If specified, the DOI that will be looked up when the popup is shown.
If not specified, DOI will be taken from the first meta tag with name dc.identifier |
| imageLocation | String | Path to location of images used by the popup. Defaults to img . |
| metadataContentType | String | Content type requested when performing DOI content negotiation. Defaults
to application/vnd.citationstyles.csl+json .
|
| metadataParser | Function | Function that will parse DOI content negotation response. Must return
a map with keys authors , title , licenses and resources . Defaults to a function that parses CSL JSON. |
| licenseLabels | Map | Map of license URLs to image filenames. Defaults to map of CC licenses |
| contentTypeLabels | Map | Map of content types (MIME types) to friendly labels. |
All options are optional!

Does mathlib have the theorem that the reals is "the unique complete archimedean field" (this can be made precise)?
I'm giving a lecture about this in 90 minutes ;-)
the uniqueness is not proved
we would need real.cast
which hasn't been defined yet
If you have any conditionally complete ordered division ring A
I think you can define a function real.cast : real -> A
by extending rat.cast
continuously. I'm not sure if that's the best constraint
If you had some kind of sequential completeness assumption, the function could probably be computable too
I think you can use dense_embedding
to extend rat.cast
if you know complete_space A
I am not necessarily going to use much Lean in this lecture, but basically the more we have the merrier.
If you have any conditionally complete ordered division ring
A
I think you can define a functionreal.cast : real -> A
by extendingrat.cast
continuously. I'm not sure if that's the best constraint
This sounds like a job for @Patrick Massot but he's probably popping the champagne after getting our paper finished ;-)

Drive Me Crazy (1999, PG-13)
Directed by John Schultz
Written by Rob Thomas
Based on the novel "How I Created my Perfect Prom Date" by Todd Strasser
Starring Melissa Joan Hart and Adrian Grenier
As Reviewed by James Brundage
The business in which I work is a nasty one. It is one of politics and of policies. Of embargoes and emissaries. Mostly, however, it is genres and grading. When grading a film, a thought brought into the forefront of your mind is "should I do this on a curve?" With a genre such as "the teen flick", something so hack that is seems to conspire towards making critics unhappy, grading on a curve would make an F an A. Since there is such a dearth of great teen flicks, and since the ones that up the curve are few and far between, I do not grade teen flicks on a curve. If I were, however, Drive Me Crazy would still get an "F"
A note to the people in Hollywood: if you are seeking to devise a movie based on a soundtrack, please be a little less obvious about it. Use said song to hype the movie but please don't share the title.  The movies in which popular artist's songs share the name (or share the refrain, in this case) of the movie are ones that rank right down their with using "based on a true story" as a tag line (see Patch Adams). They just don't fly for me.
Also on the marketing, please put it in the sub-genre that it deserves. In this case, Drive Me Crazy was advertised as a teen comedy and ended up being an oxy-moron: a teen drama. The drama level in this is akin to watching a marathon of the worst episodes of "Days of Our Lives." It isn't worth the price of the ticket.
The story of Drive Me Crazy is that of ultra-hip girl Nicole Maris (Melissa Joan Hart), who's would-be boyfriend goes for someone else instead. Distraught over this, she goes to next door neighbor Chase Hammond (Adrian Grenier), who was actually dumped by his girlfriend. The implied proposition: go to the centennial dance with me and I'll sleep with you.
I don't care if angry parents email me about encouraging amoral behavior in teens until New York goes to sleep, but this is the implication in the movie. Of course, being Hollywood this is never out-and-out stated, but it is heavily implied. The fact that it refuses to paint teens as innocents (like most PG-13 teen movies do) is Drive Me Crazy's only endearing quality.
Basically, the story goes along in an East-meets-West mentality as beatnik Chase and socialite Nicole mix, mingle, fall in love, and rehash their days in junior high. The all predictably live happily ever after. The end.

Pompeo: Iran using Islamic Jihad to strike at Israel
US Sec. of State says no one can claim to want peace in Middle East while refusing to challenge Iranian threats.
by Chana RobertsUS Secretary of State Mike Pompeo on Saturday blamed Iran for using a Gaza terror group as a proxy to attack Israel.
In two tweets, Pompeo wrote: "Iran uses its terrorist proxy Palestinian Islamic Jihad to strike our great ally Israel. Iran does not want peace in the region. It does not want the Palestinian people to prosper. It wants more conflict. Until we address Iran’s threats, the cycle of violence will continue."
"The way forward is clear: continued pressure until Iran negotiates a comprehensive agreement that includes halting its support to terror groups like PIJ. Nations around the world can no longer claim to want peace in the region yet allow Iran’s threats to go unchallenged."
Earlier this week, the PIJ launched hundreds of rockets at Israeli civilians before agreeing to a ceasefire.
On Saturday, Hamas, the terror group which controls Gaza, launched two rockets at the southern city of Be'er Sheva.

Unlimited Games. How should Red play 63?

This is a very close call. The best play is 22/13, but 22/16, 13/10 and 13/10, 8/2 are both also perfectly acceptable and very close in terms of equity.
Sometimes more than one game plan is perfectly viable and that is the case here. As the race is currently equal both plans are sensible, and it is partly a matter of style and partly estimating how well your opponent will play the resulting positions.

Next: Multiple Escape Characters, Previous: Invalid Characters, Up: Character Syntax Types
When the Lisp reader encounters a macro character on an input stream, special parsing of subsequent characters on the input stream is performed.
A macro character has an associated function called a reader macro function that implements its specialized parsing behavior. An association of this kind can be established or modified under control of a conforming program by using the functions set-macro-character and set-dispatch-macro-character.
Upon encountering a macro character, the Lisp reader calls its reader macro function, which parses one specially formatted object from the input stream. The function either returns the parsed object, or else it returns no values to indicate that the characters scanned by the function are being ignored (e.g., in the case of a comment). Examples of macro characters are backquote, single-quote, left-parenthesis, and right-parenthesis.
A macro character is either terminating or non-terminating. The difference between terminating and non-terminating macro characters lies in what happens when such characters occur in the middle of a token. If a non-terminating macro character occurs in the middle of a token, the function associated with the non-terminating macro character is not called, and the non-terminating macro character does not terminate the token’s name; it becomes part of the name as if the macro character were really a constituent character. A terminating macro character terminates any token, and its associated reader macro function is called no matter where the character appears. The only non-terminating macro character in standard syntax is sharpsign.
If a character is a dispatching macro character C_1, its reader macro function is a function supplied by the implementation. This function reads decimal digit characters until a non-digit C_2 is read. If any digits were read, they are converted into a corresponding integer infix parameter P; otherwise, the infix parameter P is nil. The terminating non-digit C_2 is a character (sometimes called a "sub-character" to emphasize its subordinate role in the dispatching) that is looked up in the dispatch table associated with the dispatching macro character C_1. The reader macro function associated with the sub-character C_2 is invoked with three arguments: the stream, the sub-character C_2, and the infix parameter P. For more information about dispatch characters, see the function set-dispatch-macro-character.
For information about the macro characters that are available in standard syntax, see Standard Macro Characters.

"There were no differences beyond the color of our skin," Volcy said. "And that's when it clicked to me … there's a reason (the TikTok algorithm is) pushing her content more than it's pushing my content."
Volcy is a Black content creator with over 120,000 followers on TikTok. She hosts the podcast Chat with Cat and is a 22-year-old college student from the Washington area. Similar to other creators, she started making TikTok videos about a month into the COVID-19 pandemic.
She started creating wellness and self-care content "randomly," she explained. At the beginning of the COVID-19 pandemic, Volcy was barely eating or getting out of bed, and creating videos helped her take care of herself.
"I was definitely targeting Black women and girls because there's not enough Black women on this app doing self-care things," Volcy said.
Volcy said Black women are usually seen in entertainment and not necessarily in beauty and wellness.
On top of her white counterparts earning more views on carbon copies of the same video, Volcy said she deals with blatant racism and racial microaggressions in the comments section.
"I'm a Black creator," Volcy said. "I'm speaking on Black issues [and] Black topics. Sometimes … (people) like me as a person that speaks to wellness and things that they need, but they don't necessarily want to hear me speak about Black issues."
With the viral nature of videos on TikTok, trends quickly pop up in the beauty community. The "That Girl" trend, commonly seen in self-care videos, encourages viewers to eat clean, practice self-care and wake up early. Creators say it is a trend that overwhelmingly represents white women, with the hashtag #thatgirl garnering six billion views on TikTok.
"It's a very pretty, white girl who's really thin, wearing … $250 workout sets and making her all-white bed," Eli Rallo, also known as @thejarr, a TikTok creator with over 540,000 followers, said. "And then having her juice in her perfect glass and her perfect toast and then doing one 10-minute workout. We don't really know what she's eating or doing in her real life."
Rallo, a college graduate living in New York City, said the frequency of this type of content has become ridiculous.
"When we are on the internet, everything is – at some level – directed," Rallo said. "People aren't showing you the fight they got in with their boyfriend this morning."
Rallo used Emily Mariko as an example of the "That Girl" aspiration. Mariko, a creator on TikTok with nearly 12 million followers, became popular for her recipe videos on the app: specifically, a spicy salmon rice bowl . In short, Mariko fits traditional beauty standards.
Rallo said if this lifestyle actually reflects your personality, that is fine.
"I'm attacking the way that other people aspire to be that when it's really hard to do and unrealistic," Rallo said. "You can't aspire to be that if you work three jobs to put food on the table.
Rallo also pointed out that very few videos in this trend are made by women of color, plus-size women or trans women.
"None of them are falling into any minority communities," Rallo said. "They are the beauty standard. It started to frustrate me because if I tried to make that video, I can't explain to you how much it would not f––ing work. My sheets are purple, and there is blood on them because I can't get it out … I love glitter, my American Girl (dolls) are sitting right to my left, I have stacks of books everywhere."
Instead of aspiring to be "That Girl," Rallo's motto is to focus on "This Girl." The message is one of self-love, self-worth and acceptance.
Rallo also spoke on how trends such as "That Girl" lack diversity and are rooted in misogyny. If a "That Guy" trend existed, Rallo thinks it would look like rock 'n' roll, sex, money and power.
For women, becoming "That Girl" encourages girls to shrink themselves, to become not only physically smaller but also lead a minimal lifestyle, Rallo said.
"Sure, on some level, there would be some toxic stuff," Rallo said. "You would still see the money, that wouldn't go away – the classism that's embedded in this."
Matthew Campos, a creator on TikTok with over 454,000 followers, creates short daily vlogs of his day that often feature self-care content such as his skincare routine, cleaning and meals. However, Campos said there are not nearly enough self-care resources for men.
"There is definitely not enough representation," Campos said. "(The) vast majority are definitely women. And I think us as men can definitely take advantage of this. It is something that can help you in the future – taking care of your skin now, taking care of your body."
Campos said he started creating videos on TikTok in October 2021 because he has always been interested in photography and videography. He started getting into self-care through his mom, sister and girlfriend.
Campos said he is not sure what kind of content box he fits into, but his wellness and skincare are what get the most attention.
"Just seeing how many people question me on a day-to-day basis on my videos, 'Hey, what's your skincare routine?' or 'Hey, what products do you use?'" he said. "And shockingly, it's mostly men. I think it's because they see another guy doing it and they can relate to that."
Campos said he interacts and follows men of color who create self-care content. Nevertheless, he agreed the space needs to be more inclusive.
"My family are immigrants, so I just always gravitated toward that," Campos said. "I just followed creators that either look like me or I would be friends with, people that I'm similar to or that [I] relate to."
Alexis Ky, a senior at Ohio University studying nursing, said she sees an increase in diversity and wellness content online, specifically in Asian representation. As Thread Magazine's makeup director, she consumes a ton of beauty content on social media.
"Because I am of Asian heritage, I would say [my social media] is pretty diverse because I go out of my way to look for it," Ky said.
She attributed an increase in representation to aspects of Asian culture becoming more popular in the U.S. Trends such as Korean skincare routines, bucket hats and Chinese street fashion are becoming more mainstream, she said. Despite this, Ky still feels like she has to search for it.
"We do not focus too much on where our trends are coming from," Ky said. "Like Gua Sha – we know it's an ancient Chinese beauty routine, but I feel like a lot of people don't actually know the history behind it. Same with other fashion trends like body chains, people don't focus on where that originated from … My issue with stuff like that is that we just go along with it, but don't appreciate how it came to be."
She encouraged others to research these trends and ask questions to those part of specific cultural groups. In turn, this fosters cultural appreciation rather than appropriation.
"Not everyone's culture should be a trend," she said. "If you're only doing it because you like the way it looks, you're not actually appreciating where it's coming from and the way people live."
Amaya "Mickey" Serbia, a junior at OU studying marketing and business analytics, said she grew up consuming beauty content online, citing influencers like Patrick Starr, Manny MUA and Bretman Rock. Now, she works as a Campus Representative for Victoria's Secret PINK and does makeup for Thread Magazine.
"Now, I would say I start to watch a lot on TikTok and Instagram, those are definitely my top two," she said. "I definitely see myself consuming both of those not only for entertainment purposes and education, but just to see what people enjoy so that I can apply that with my job."
Serbia is also the president of El 787, a club created for students of Puerto Rican descent.
"Being Puerto Rican, I see a lot of Puerto Rican content creators, especially in beauty since that's something I really do enjoy," Serbia said.
Serbia said that as a white Latina, she relates to content creators who receive similar comments.
"It does shock people sometimes that you can be white and Latina," she said. "Now, I'm seeing more Puerto Ricans that look like me … They always get the, 'Oh, you don't look Latina' comment all the time.'"
In addition to this representation, Serbia said she also sees trends that are not inclusive or appropriate. She cited the "clean girl aesthetic " trend on TikTok that encourages gold jewelry, a neutral color palette, a fresh face and slicked-back hair.
"A lot of Latinos, specifically women, are voicing their opinion on how that was what they grew up looking like with the slick back bun," Serbia said. "All this 'clean girl aesthetic' stuff that now is popular because white girls did it."
The solution? Increased transparency. Serbia said this is why influencers like Emma Chamberlain are so popular, because of their authenticity.
"Of course, your day-to-day life doesn't look like that," Serbia said. "Now with the influx of people wanting to be influencers and content creators, you can tell when people are being disingenuous … if you're lying about that stuff, think about all the girls who have eating disorders or are self-conscious about themselves because they see that [content] and think it's real."
Serbia also encouraged creators to listen to their followers who are a part of minority groups when taking part in trends with cultural roots. She also said creators should be held accountable online.
"You need to be talking about and drawing attention to this, and you also need to be simultaneously holding the door for creators that don't have the same privileges," Rallo said, speaking from a creator perspective.
Volcy echoed Rallo's concerns that wellness content can not only be unachievable and unattainable, but especially harmful to young users.
"They are extremely impressionable," Volcy said. "They are like, 'Hey, I don't look like that, so I can't be that.' To me, it can distance wellness from people … I've never not once captioned or hashtagged 'That Girl.'"
Volcy said she understands why this content continues to be perpetuated by creators because it gets views. Still, Rallo encourages other creators with privileges, should they be white, thin or conventionally attractive, to use their influence for good.
"If you have a day where you sleep in, or you don't feel good, or you don't work out, or you eat f––ing McDonalds, for god sakes, that's all allowed," Rallo said.

28 The rest of the people made a solemn agreement, including the priests, gatekeepers, singers, and temple workers. They also included all the men from other neighboring peoples who had left their people and were living in Israel. These men, along with their wives, their sons and daughters who were old enough to understand what they were doing, promised they would obey God's law.
29 They all joined with their leaders in making this solemn agreement. They agreed to obey all the laws that God had given to Moses. They agreed to follow and to obey everything that Yahweh our God had commanded, and all his decrees and instructions. They promised to do the following.
30 "We will not allow our daughters to marry people who live in this land who do not worship Yahweh, and we will not allow our sons to marry them.
31 If people from other countries who live in this land bring us grain or other things to sell to us on Sabbath days or any other sacred day, we will not buy anything from them. And in every seventh year, we will give rest to the fields and we will not plant any crops that one year, and we will cancel all debts to other Jews.
32 We each also promised ourselves that every year we will pay about 5 grams of silver for those who serve and take care of the temple.
33 With that money they can buy these things: The bread on display before God, the flour that is offered to God by burning it on the altar each day, the animals that were killed and completely burned on the altar, the sacred offerings for the Sabbath days and for celebrating the new moons and other festivals and offerings that are dedicated to God, the animals to be sacrificed to pay the penalty for the sins of the people of Israel, and anything else that is needed for the work of taking care of the temple.
34 Each year the priests, the descendants of Levi who help the priests, and the rest of us will cast lots to determine for that year which families within the Levites will provide wood to burn on the altar to burn the sacrifices in the house of our God, as it is written in the law of God.
35 We promise that each year each family will take to the temple an offering from the first food that we grow in our soil and harvest for food, and from the firstfruits that grow on our trees that year.
36 We will take to the house of God our firstborn sons and we will also bring firstborn calves and lambs and baby goats to be dedicated to God. That is what is written in God's laws that we must do.
37 We will also take to the priests at the temple the flour made from the first grain that we harvest each year, and our other offerings of wine, olive oil, and fruit. We will also take the tithes to the descendants of Levi who help the priests.
38 A priest, one who is a descendant of Aaron, will be with the the Levites and supervise them when they collect the tithes. Then the descendants of Levi must take a portion of it, ten percent of the things that people bring, and put it in the storerooms in the temple.
39 The descendants of Levi and some of the people of Israel must take the offerings of grain, wine, and olive oil to the storerooms where the various utensils are kept that are used by those who serve in the temple. That is the place where the priests who are serving at that time, the gatekeepers, and where those who sing in the temple choir, live.
We promise that we will not neglect taking care of the temple of our God."

But natural numbers can equally well be taken to be answers to the question "how many times" or "how often". This is how they are treated in Church's lambda calculus. They are functions which take a unary function as argument and return a unary function as value. If the argument function is the squaring function, and the number in question is three, then the returned function computes the square of the square of the square. So numbers are second order functions. But since they are unary functions, they can be applied to themselves at least in the untyped lambda calculus. So numbers are also third order functions, and so forth - they are simply higher order functions.
Numbers must be distinguished from numerals or more generally, numeric expressions. The numerals "7", "seven", "sept", "VII" and also the expressions "3+4" and "10-3" are all different, and yet they denote the same natural number. The so-called Church numerals of the lambda calculus are expressions which denote higher order functions of the kind described above. The remainder of this note shows how Church numerals can also be expressed in Joy.
First, the Church numeral C0, which is to execute the quoted program [P] zero times. Clearly this is achieved by just popping off the quoted program.
The other Church numerals will have to be constructed from C0 together with Csucc, a successor function for Church numerals. This function Csucc will take as parameters a quoted Church numeral, say Cn, and below that whatever quotation is to be executed repeatedly. So a program of the form ... [P] [Cn] Csucc should execute [P] exactly (n+1) times. This can be done by executing [P] once, and then again n times. So Csucc should first execute a copy of [P] and then allow Cn to execute [P] n times.
Here are the definitions of C0 and Csucc:
DEFINE C0 == pop; Csucc == [dup [i] dip] dip i.Church numerals do not denote numbers as data values but numbers as repetitions of execution of a program. So they need a program [P] to be repeated zero or more times. Preferably the output should bear some resemblance to what is being tested. A good choice is the ordinary successor function succ for ordinary numbers, to be called zero or more times with the ordinary number 0 on top of the stack.
DEFINE Peano == 0 [succ].Here are the obvious tests:
Peano C0. 0 Peano [C0] Csucc. 1 Peano [[C0] Csucc] Csucc. 2 Peano [[[C0] Csucc] Csucc] Csucc. 3It is convenient to introduce definitions for the first few positive Church numerals. The tests follow.
DEFINE C1 == [C0] Csucc; C2 == [C1] Csucc; C3 == [C2] Csucc.
Peano C0. 0 Peano C1. 1 Peano C2. 2 Peano C3. 3Instead of using the natural numbers, with 0 and [succ], for tests of the Church numerals, we can also use many others data structures. Here are two examples:
DEFINE Doublings == 1 [2 *]; Lists == [] [[i] swoncat].
Doublings C0. 1 Doublings C1. 2 Doublings C2. 4 Doublings C3. 8
Lists C0. [] Lists C1. [i] Lists C2. [i i] Lists C3. [i i i]
To add two numbers m and n, we can take the n-th successor of m. This is also what the definition of Cadd below will do. It will transform the quotation [Cm] into another quotation by repeatedly constructing the successor quotation, where the number of repetitions is given by [Cn] which is called by the first i. The reculting quotion is then called by the final i.
To multiply two numbers m and n, we can start with 0 and add m exactly n times. To exponentiate, to compute m to the n-th power, we start with 1 and multiply by m exactly n times. This is also what the definitions of Cmul and Cpow do. They are more complex than the definition for Cadd for two reasons: the starting values C0 and C1 have to be specified, and also the operations Cadd and Cmul which they use are binary. The starting values are quoted, as [C0] and [C1] respectively, and they are squeezed below the [Cm] and [Cn]. At the same time [Cm] is transformed into either [[[Cm] Cadd] cons] or [[[Cm] Cmul] cons] respectively. This is then repeatedly executed, where the number of repetitions is given by [Cn] which is calle by the first i. The resulting quotation is then called by the final i.
Here follow the definitions and two forms of tests.
DEFINE Cadd == [ [[Csucc] cons] ] dip i i; Cmul == [ [[C0]] dip [Cadd] cons [cons] cons ] dip i i; Cpow == [ [[C1]] dip [Cmul] cons [cons] cons ] dip i i.
Peano [C2] [C3] Cadd. 5 Peano [C2] [C3] Cmul. 6 Peano [C2] [C3] Cpow. 8
Doublings [C2] [C3] Cadd. 32 Doublings [C2] [C3] Cmul. 64 Doublings [C2] [C3] Cpow. 256The operators can of course be used in complex expressions, as in these examples. The first just computes a value, and the second compares the same value with the identical value obtained from ordinary arithmetic.
Peano [[[[[C3] Csucc] [C2] Cadd] [C3] Cmul] Csucc] [C2] Cadd . 21 Peano [[[[[C3] Csucc] [C2] Cadd] [C3] Cmul] Csucc] [C2] Cadd 3 succ 2 + 3 * succ 2 + = . trueAs the second example shows, the value computed using Church arithmetic is the same as the one using ordinary arithmetic. However, the example also shows up how complex the expressions using Church arithmetic become when compared with ordinary expressions. This is because the Church operators need quotations as parameters, and hence the Church expression contains many square brackets whereas the ordinary expression requires none. So it seems that the quotation brackets are performing somewhat the same role as the ordinary grouping parentheses are performing in infix notation.
It is of some interest to see whether this is an inherent problem with expressing Church arithmetic in Joy, or whether there is a way of expressing Church arithmetic in Joy that retains the usual bracket free notation of Joy as for ordinary arithmetic.
The remainder of this section defines quotation numerals and quotation operators in the same sequence as in the two preceding sections.

Peano Q0 i. 0 Peano Q1 i. 1 Peano Q2 i. 2 Peano Q3 i. 3Since Church numerals denote (higher order) functions, they cannot be written - they do not have a finite representation. However, this is not true of the quotation numerals as just defined - these can be written since they are just quoted programs to compute such functions. Here are the first four quotation numerals:
Q0. [pop] Q1. [[pop] [dup [i] dip] dip i] Q2. [[[pop] [dup [i] dip] dip i] [dup [i] dip] dip i] Q3. [[[[pop] [dup [i] dip] dip i] [dup [i] dip] dip i] [dup [i] dip] dip i]
The quotation operators for addition, multiplication and exponentiation are just like the quotation operator Qsucc: they expect quotations as parameters and produce quotations as results.  A few tests also follow.
 As can be seen, there are no quotation brackets visible, and as the second example shows, the whole structure of the expression is identical to the ordinary postfix expression for ordinary arithmetic.
Peano Q3 Qsucc Q2 Qadd Q3 Qmul Qsucc Q2 Qadd i. 21 Peano Q3 Qsucc Q2 Qadd Q3 Qmul Qsucc Q2 Qadd i 3 succ 2 + 3 * succ 2 + = . true
Here are the definitions of the two Church truth values, also two pairs of functions, and of course some tests.
DEFINE Ctrue == pop i; Cfalse == popd i.
DEFINE Boole == ["Yes, yes"] ["No, no"]; Comparison == 2 3 [<] [>].
Boole Ctrue. "Yes, yes" Boole Cfalse. "No, no" Comparison Ctrue. true Comparison Cfalse. falseThe negation operator for Church truth values will take as its parameter a quotation which, when executed, will expect two quotations on the stack. In analogy with the definition of Church negation in the lambda calculus, the Cnot operator for Church truthvalues in Joy might be defined as
DEFINE Cnot == [ [Cfalse] [Ctrue] ] dip i.However, because Joy is stack-based, a much simpler definition results if the Cnot operator simply swaps the two quotation parameters below the Church truth value, as follows.
DEFINE Cnot == swapd i.
Boole [Ctrue] Cnot. "No, no" Boole [Cfalse] Cnot. "Yes, yes" Comparison [[Ctrue] Cnot] Cnot. true Comparison [[Cfalse] Cnot] Cnot. falseThe definition of the two binary operators on Church truth values look quite different from the binary operators on Church numerals. This is because Church truth values take two quotation parameters, whereas Church numerals only take one. Apart from that, the definitions of the disjunction and conjunction operators on truth values are actually simpler than those for Church numerals.
Both operators expect two quotations denoting Church truth values. Both may need to be executed to determine the result of the binary operation. In the case of disjunction, Cor, if the evaluation of the top quotation yields Ctrue, then the other quotation will be discarded and the quotation below that will be executed. That will have to be the quotation [Ctrue], which will have to be placed there before Cor can execute the top quotation. On the other hand, if the evaluation of the top quotation yields Cfalse, then the added quotation [Ctrue] will be discarded and the second quotation will be executed whose result then fully determines the result yielded by Cor. Since the second quotation is only executed when its result is needed, this definition of Cor is what is sometimes called a "short circuit" implementation.
The definition of Cand is entirely analogous. The four tests for Cor and for Cand also follow.
DEFINE Cor == [[Ctrue]] dipd i; Cand == [[Cfalse]] dip i.
Boole [Ctrue ] [Ctrue ] Cor. "Yes, yes" Boole [Ctrue ] [Cfalse] Cor. "Yes, yes" Boole [Cfalse] [Ctrue ] Cor. "Yes, yes" Boole [Cfalse] [Cfalse] Cor. "No, no" Boole [Ctrue ] [Ctrue ] Cand. "Yes, yes" Boole [Ctrue ] [Cfalse] Cand. "No, no" Boole [Cfalse] [Ctrue ] Cand. "No, no" Boole [Cfalse] [Cfalse] Cand. "No, no"
Below is the definition of just one such predicate, the unary predicate Ceq0 which tests whether its parameter on the top of the stack is equal to zero, or better: whether it is C0. In the case of equality Ceq0 has to behave like Ctrue, otherwise it has to behave like Cfalse. To perform the test, it has to execute its parameter, which is a quotation [Cn] of a Church numeral or a quotation which eventually yields such a numeral. Below that parameter has to be a quotation which might not be executed at all if n=0, but might be executed many times. In the first case, when n=0, the Church numeral C0 has already been executed, and the redundant quotation has already been popped, but now Ctrue has to be executed. In the other cases, when n is positive, the Church numeral will have executed a a quotation several times, but now Cfalse has to be executed.
The definition below will do just that. First, below the quotation [Cn] it inserts two other quotations, [Ctrue] and [pop [Cfalse]]. The second of these may be executed zero or more times. The first time, if ever, it will replace the [Ctrue] by [Cfalse], and any further time it will replace the [Cfalse] it has placed there last time by a new [Cfalse]. After these two quotations have been inserted below the quoted Church numeral [Cn], the first i executes [Cn], resulting in either the original [Ctrue] or a [Cfalse] to become the top element on the stack. Finally, the second i executes that, as required.
After the definitions there are some obvious tests, and the last two also use the equality predicate in expressions using Cor and Cand.
DEFINE Ceq0 == [ [Ctrue] [pop [Cfalse]] ] dip i i.
Boole [C0] Ceq0 . "Yes, yes" Boole [C1] Ceq0 . "No, no" Boole [C2] Ceq0 . "No, no" Boole [[C0] Ceq0] [[[C2] Csucc] Ceq0] Cor. "Yes, yes" Boole [[C0] Ceq0] [[[C2] Csucc] Ceq0] Cand. "No, no"The Church truth values expect two quotations on the top of the stack, and depending on which truth value it is, one of the quotations will be discarded and the other will be executed. So they implement a simple version of branching. A more useful one would expect a third quotation on the stack that is executed to determine which of the other two is to be executed. The third quotation, the if-part, could be above of below the other two, the then-part and the else-part. For efficient execution the if-part should be on top, to be executed by the combinator i. On the other hand, for analogy with the ordinary combinator ifte, it is best if the if-part is the third element on the stack. In the following definition of a Church combinator Cifte, the if-part is moved to the top by rolling down the other two parts. Following that, the if-part is executed by the i combinator.
Several examples also follow. The later examples, which use Church conditionals nested within Church conditionals, are written over several lines for ease of reading.
DEFINE Cifte == rolldown i.
Peano [[C0] Ceq0] [C2] [C3] Cifte. 2 Peano [[C1] Ceq0] [C2] [C3] Cifte. 3 Peano [[[C0] Ceq0] Cnot] [C2] [C3] Cifte. 3 Peano [[[C1] Ceq0] Cnot] [C2] [C3] Cifte. 2
Peano [Ctrue ] [[Ctrue ] [C0] [C1] Cifte] [[Ctrue ] [C2] [C3] Cifte] Cifte. 0 Peano [Ctrue ] [[Cfalse] [C0] [C1] Cifte] [[Cfalse] [C2] [C3] Cifte] Cifte. 1 Peano [Cfalse] [[Ctrue ] [C0] [C1] Cifte] [[Ctrue ] [C2] [C3] Cifte] Cifte. 2 Peano [Cfalse] [[Cfalse] [C0] [C1] Cifte] [[Cfalse] [C2] [C3] Cifte] Cifte. 3Church truth values are actually very similar to the two operations which select one or the other from a pair of objects. The "dotted pair" constructor cons in Lisp and Scheme builds a pair of objects from its two parameters. The two operators car and cdr select the first or the second from such a pair. The last sentence just about captures the semantics of the constructor cons and the two operators. Any implementation must capture this semantic condition, but otherwise any further detail of the implementation is immaterial.
The following define a constructor Ccons and two operators Ccar and Ccdr. The latter use the Church truth values Ctrue and Cfalse to effect the selection from a pair constructed by Ccons. Ccons of course expects two parameters on the top of the stack, but since there is no requirement that the two be wrapped into one parcel, it does not do so. Instead it just pushes the sligtly curious quotation [i]. This will be executed by the call to the i combinator in Ccar and Ccdr, and that will result in either Ctrue or Cfalse being executed, depending on which one caused the execution of [i].
Note that Ccons is more general than the cons operator on Joy which requires its topmost parameter to be a list.
The last four examples are again written over several lines for ease of reading. They are the four list-counterparts of the four conditionals of the previous examples.
DEFINE Ccons == [i]; Ccar == [Ctrue] swap i; Ccdr == [Cfalse] swap i.
Peano [C0] [C1] Ccons Ccar. 0 Peano [C0] [C1] Ccons Ccdr. 1
Peano [[C0] [C1] Ccons Ccar] [[C2] [C3] Ccons Ccar] Ccons Ccar. 0 Peano [[C0] [C1] Ccons Ccdr] [[C2] [C3] Ccons Ccdr] Ccons Ccar. 1 Peano [[C0] [C1] Ccons Ccar] [[C2] [C3] Ccons Ccar] Ccons Ccdr. 2 Peano [[C0] [C1] Ccons Ccdr] [[C2] [C3] Ccons Ccdr] Ccons Ccdr. 3
The definitions of Church concepts in Joy, like the corresponding concepts in the lambda calculus, are mainly of theoretical interest. So far none of the definitions have been found useful in practical programming in Joy. Accordingly none of the definitions have been included in any of the libraries. However, the Joy source for this note, without the text, is available on: jp-church.joy
Church numerals and related matters are treated in many of the more theoretical books dealing with functional languages based on the lambda calculus. There is also a vast literature available online, a web search for "Church numeral" will find many excellent expositions.
Shortly after I put the preceding sections on the web page for Joy, on 9-Oct-2002 Brent Kerby sent a note to the "concatenative" mailing list. The remainder of this section is the first part of his note.
About the construction of Csucc (which adds one to a church number), Csucc == [dup [i] dip] dip i. this can be simplified a bit: Csucc == [dup dip] dip i. because "dup [i] dip" is the same as "dup dip"; by the way, the "dup dip" combinator is an interesting one; I call it "run", since it in effect executes a program without destroying the program.
# The original definitions, commented away, are given for comparison. # Brent Kerby's new definitions over-ride the old ones.  # Now the old tests using the new definitions: Peano [C2] [C3] Cadd. 5 Peano [C2] [C3] Cmul. 6 Peano [C2] [C3] Cpow. 8 Doublings [C2] [C3] Cadd. 32 Doublings [C2] [C3] Cmul. 64 Doublings [C2] [C3] Cpow. 256 Peano [[[[[C3] Csucc] [C2] Cadd] [C3] Cmul] Csucc] [C2] Cadd . 21 Peano [[[[[C3] Csucc] [C2] Cadd] [C3] Cmul] Csucc] [C2] Cadd 3 succ 2 + 3 * succ 2 + = . true
This section is verbatim the second part of his note.
By the way, there are several other ways of doing church numbers in Joy. The current way assumes, [p] Cn == p p ... p But alternatively we could do: [p] Rn == p p ... p [p] The only difference here is that we save the original program "p". The principal advantage of this approach is that then Rn are reversible combinators (note, Cn were all irreversible combinators since they destroy the original program).  This is quite an elegant setup, seeing that simply "run" acts as a successor function, and C0 is simply the empty program. Also, the negative church numbers then are R-1 == unrun R-2 == unrun unrun R-3 == unrun unrun unrun ... Note the reverse of any church number then is simply its negative. Also, to add church numbers is simply to concatenate them. Of course, "cat" itself is irreversible, so we might use "rat": [b] [a] rat == [b a] [a] This is a suitable addition function for the Rn church numbers; notice it preserves one of the parameters, like a reversible addition function should. Also, unlike Cadd, it does not execute the newly formed program (doing so would be irreversible, as "i" is irreversible). Here's how to multiply these Rn church numbers: Rmul == swap cons untack It works, for example, like this: [2] [3] swap cons untack == [[3] 2] untack == [3 3 [3]] untack == [3 3] [3] == [6] [3] So that's nice, except that this is not really reversible, since "cons" is not reversible (assuming we have transparent quotation; if we have opaque quotation then "cons" is reversible, but the multiplication then doesn't work because "untack" fails): [a] [dup] cons == [[a] dup] == [[a] [a]] [[a] [a]] [] cons == [[a] [a]] See how cons can give the same result from different inputs? This means it is irreversible. So can Rmul be defined from reversible primitives? If so, we would expect to fail in the case of multiplying by zero, since that is irreversible. Also, having a reversible Rmul would give us the ability to do division, and the ability to construct fractional church numbers. But do fractional church numbers make sense? For example, the church number for 1/2 would have the rule: [a a] R1/2 == a [a a] In a system with transparent quotation, it seems like R1/2 would not be straightforward to implement, perhaps impossible, since it would require the system to try to coerce an arbitrary "[p]" into the form "[a a]", by using reductions and expansions inside the quotation. But maybe there is some reasonable way to do it ... - Brent
[ a propos my question: ] > Could you clarify why you say that your Cpow is not a true combinator? Well, it's pretty simple, really. When we try to write a "reduction rule" for Cpow, the best we can get is this: [p] [m] [n] Cpow == [p] [[m] cons] n i Note the appearances of "cons" and "i" on the right hand side. This is in essence what makes it a pseudo-combinator. A true combinator has a reduction rule without such things on its right hand side, for example: [a] dup == [a] [a] [b] [a] swap == [a] [b] [p] [n] Csucc == p [p] n [p] [m] [n] Cadd == [p] m [p] n [p] [m] [n] Cmul == [[p] m] n See how in all of these the right hand side consists solely of variables, mixed up through concatenation and quotation. That is why they are called true combinators, because they possess a reduction rule of this kind. For the curious, there is some interest in a system that contains only true combinators, no pseudo-combinators. Such a system would have to get rid of quotation, since the quotation of any combinator is a pseudo-combinator (e.g., "[dup]" or "[swap]" is a pseudo-combinator, since it possesses no reduction rule). This idea hasn't been fully explored, but you might like to look back on the post http://groups.yahoo.com/group/concatenative/message/1051 and other posts thereabouts. The idea is that a workable base is {nil, zap, dup, i, unit, take, cat}: nil == [] [a] zap == [a] dup == [a] [a] [a] i == a [a] unit == [[a]] [b] [a] take == [a [b]] [b] [a] cat == [b a] I suspect that all true combinators can be constructed form these, using concatenation alone (no quotations allowed), and there is very probably a smaller base that will work. Here's a few examples of some constructions in this system (a searcher reveals that these are the minimal constructions): dip == take i swap == unit take i flip == unit take take i (i.e., a combinator that reverses the top 3 items) dupd == unit take i unit dup cat take i == unit take i dup unit take take i sip == unit take i unit dup cat take i take i == unit take i dup unit take take i take i More simply, we could have dupd == swap dup flip sip == dupd dip [ a propos another question from me: ] > I do remember that in one reference (I cannot remember which, alas) > it was pointed out that exponentiation could be implemented > as applying the exponent n to the base m, but that was > considered "cheating" [sic]. I did not understand that > either, but maybe you are talking about the same thing. Yes, in the classical combinatory logic you can exponentiate Church numbers simply by applying them (although it is the base that is applied to the exponent, not the other way around). We can do the same thing in Joy if we reform the Church numbers once more (I'll call them Zn, as that is what the Church numbers are standardly called): [x] [p] Zn == [[[[[x] p] p] ...] p For example, [x] [p] Z0 == x [x] [p] Z1 == [x] p [x] [p] Z2 == [[x] p] p Note these Church numbers take two parameters as opposed to the one parametered Cn and Rn.  Anyhow, these Zn seem to be the true analogue of the classical Church numbers, although that's not to say that they are necessarily the most appropriate in a concatenative system. But, Zn do have use; for example, dip2 == [dip] Z2 dip3 == [dip] Z3 dip4 == [dip] Z4 ... See, [p] dip3 == [p] [dip] Z3 == [[[p] dip] dip] dip That seems pretty handy.


Eddie May in Hibs 'commitment' poser as he makes veiled Paul Heckingbottom dig
The academy chief is in the dugout for today's clash with St Johnstone but doesn't want the job permanently.
by Gabriel McKayHibs caretaker manager Eddie May has offered a veiled jibe about Paul Heckingbottom 's style of play as he appeared to question the commitment of some of his signings.
The Englishman was sacked by the club this week, with the academy boss taking charge for today's trip to St Johnstone .
He's made five changes from the team which lost 5-2 to Celtic in Heckingbottom's last game, with Thomas James, Adam Jackson, Daryl Horgan, Stevie Mallan and Josh Vela dropping out.
James, Jackson and Vela were all summer signings, and Florian Kamberi has been restored to the XI for only his second start since September.
May said: "I've looked at the games where we've been competitive and I want players who are committed to the club.
"I want players who are good on the ball and people who are attacking. It's just unfortunate that some guys have missed out today but they're part of a squad and everyone will get their opportunity. If things aren't going well we can put some of these players on.
"We have to take responsibility on the park in terms of delivering a more pleasing on the eye product but also more attacking.
" Hibs have probably been a little bit unfortunate in some games, they could be a few points better off, but we're not and we have to make sure that we go out and make a difference on the park.
"We've picked a team that suits us."
May is in caretaker charge for today's game but made clear he has no interest in taking the job permanently.
He added: "I think I've already stated that. I'm in for a reason, someone has lost their job which is unfortunate and someone else will come in and take the club forward.
"It's not about me it's about what's best for the club and there are some very good candidates who want the job so I think they have to go and look at everyone and then make the right decision."

Syntax:
list &rest objects => list
list* &rest objects+ => result
Arguments and Values:
object---an object.
list---a list.
result---an object.
Description:
list returns a list containing the supplied objects.
list* is like list except that the last argument to list becomes the car of the last cons constructed, while the last argument to list* becomes the cdr of the last cons constructed. Hence, any given call to list* always produces one fewer conses than a call to list with the same number of arguments.
If the last argument to list* is a list, the effect is to construct a new list which is similar, but which has additional elements added to the front corresponding to the preceding arguments of list*.
If list* receives only one object, that object is returned, regardless of whether or not it is a list.
Examples:
(list 1) => (1) (list* 1) => 1 (setq a 1) => 1 (list a 2) => (1 2) '(a 2) => (A 2) (list 'a 2) => (A 2) (list* a 2) => (1 . 2) (list) => NIL ;i.e., () (setq a '(1 2)) => (1 2) (eq a (list* a)) => true (list 3 4 'a (car '(b . c)) (+ 6 -2)) => (3 4 A B 4) (list* 'a 'b 'c 'd) == (cons 'a (cons 'b (cons 'c 'd))) => (A B C . D) (list* 'a 'b 'c '(d e f)) => (A B C D E F)
Side Effects: None.
Affected By: None.
Exceptional Situations: None.
