13:21 stamourv: there's the Y combinator
13:21 samth: (letrec ([f (lambda (x) (if (zero? x) 1 (f (sub1 x))))]) f)
13:21 stamourv: but it's easier to bind the function (with define or letrec)
13:23 Yann1: Okay, I thought there may be a macro for this. thanks
13:24 samth: there is `rec' from `mzlib/etc'

16:07 ti84: hello world! :D
16:23 clklein: Is there something like LaTeX's enumerate in Scribble?
16:24 clklein: (or like itemize)
16:24 clklein: oh, nevermind
16:24 clklein: The connection with itemize helped me find the right query :)

17:06 ti84: hello ! I'd like to make a function which would do that : (f   '(1 2 3)  '(4 5 6) ) --> ((1 2 3) (4 5 6))  any idea ? thx
17:07 ti84: so I give 2 (or more....) lists, and it gives me a list of the lists
17:09 jonrafkind: list
17:09 jonrafkind: (list '(1 2 3) '(4 5 6)) => ((1 2 3) (4 5 6))
17:10 ti84: oh... ok :)  I feel stupid now xD

17:50 Quetzalcoatl_: Is there a way to get rid of flickering in Racket's GUI library?
17:50 Quetzalcoatl_: Example: http://codepad.org/jE9cHp4k
17:51 samth: with which version?
17:51 Quetzalcoatl_: 5.0.2
17:51 Quetzalcoatl_: Windows XP.
17:52 samth: i see no flicker on 5.0.99
17:52 samth: on linux
17:53 samth: you should try a current nightly build, and see if it still flickers
17:53 samth: if so, report it on the mailing list
17:53 ti84: I've got a problem !! :( if I write (define L '( (1)  (2)  (3)  '( )  ))  and then (list-ref L (- (length L) 1)) it says '( )  [that, is normal]. But if I write (equal? (list-ref L (- (length L) 1))  '( )) it returns #f !!! I don't get it...
17:54 samth: you have an extra ' in the definition of L
17:55 samth: you'll note that the result of the list-ref is ''() (note the extra ')
17:55 (quit) sstrickl: Quit: sstrickl
17:56 ti84: I don't see that... o.O
17:57 samth: where don't you see that?
17:57 samth: the result of (list-ref L (- (length L) 1)) is ''() at the Racket REPL
17:57 ti84: you mean that L should be '( (1) (2) (3) ( )) ?
17:59 ti84: ok, it works !!! thanks :)
17:59 samth: yes, that's what it should be
18:01 ti84: thank you!

18:30 jonrafkind: i have this expression which looks like its not type-correct, but agda doesn't complain about it
18:30 clklein: I'll give it a shot.
18:31 Quetzalcoatl_: samth: You received it?
18:31 samth: yes
18:31 Quetzalcoatl_: The bug reporting tool seems to be hung.
18:31 samth: yeah, it does that to me sometimes too
18:32 Quetzalcoatl_: Hmm..
