I wrote an explanation of why until=<<((==)=<<) is a fix point function, which might be of interest for new Haskell learners: codegolf.stackexchange.com/a/144402/56433

Also any idea if there is a shorter version without the import?

The shortest version without imports that I have found is 65 bytes: Try it online!

One thing to keep in mind is that until=<<((==)=<<)$f is actually a byte longer than until(\x->x==f x)f. So it only saves some bytes if f can be expressed point free without auxiliary functions.

You should totally change the room description from "For discussions about..." to "For little talks about..." ;)

Icelandic

and "Monsters" is phonetically closer to "Monads" than "Mice" is :P

(or going by Levenshtein distance...)

wait that might not be true

hm yeah, they're both 5 by Levenshtein... well.

@Laikoni I have the impression you use =<< more often than >>=, is there a reason?

I've actually been wondering a lot why there is fixed point built in!

I found myself using until(f>>=(==))f so many times.

(I actually asked this on SO a while back: stackoverflow.com/questions/38955348/… ) (Why don't you add the until=<<((==)=<<) solution there too? :)

CMS (Chat Mini Survey): What editors or IDEs do you use for Haskell?

@flawr For this specific example I use this direction because f (g x) x = (f=<<g)x keeps the order of f and g. In general I can't think of a reason, maybe I do it unconsciously.

Though I have to admit that ((==)=<<)>>=until also looks kind of neat, though even more unclear.

@Laikoni Would be hilarious if you could operatorify a parenthesis

As long as someone else writes the parser, sure. :D

@flawr Sublime Text and TIO.

Even though there are some annoying syntax-highlighting bugs in sublime text.

@Laikoni do you use haskell regularly outside of golfing?

@flawr Emacs with haskell-mode, or TIO when golfing.

@flawr No, except sometimes as a calculator.

@flawr I use Vim and TIO. TIO for short programs and Vim for long ones.

So what should I use, sublime emacs or vim? :D

I don't know about you. I'm don't like most of the things people like in their IDEs, I find colors and syntax completion annoying so I try to go as vanilla as possible

I also like Vim

I have to admit, I'm rather proud about outgolfing Mathematica, JavaScript and Python by 85 to over 200 bytes on this challenge.

@Laikoni Is there a reason you chose ((unlines.snd).).(#) over x&y=unlines$snd(x#y)

I think I had the one byte longer x&y=(unlines.snd)$x#y before, so pointfree looked shorter.

Ah, also some other solutions are outputting lists of strings.
