08:03 Girffe: Hey, I was wondering if racket has a function that gets a random element of a list
08:04 Girffe: It's pretty trivial to write with (random), I'm just wondering if it's already defined in the language
08:04 (join) ambrosebs
08:04 eli: Girffe: No, but it's really trivial.
08:05 eli: samth_away: it might depend on the environment somehow, it's a low-level thing, almost like expect.
08:06 Girffe: Yeah, it's just a bit of a shame, (random-list) would probably be used more often than (random).
08:21 eli: Girffe: What would such a `random-list' do?
08:22 Girffe: Just return a random element of a list
08:22 Girffe: i.e. (define (random-list lst) (list-ref lst (inexact->exact (floor (* (random) (length lst))))))
08:23 Girffe: I think most of the time people would use (random) in racket, they're just using it to get a random element of a list anyway
08:24 eli: Girffe: (a) in racket (and in scheme and lisp) we don't use "(foo)" as a way to say that foo is a function -- so it's not like using "foo()" in c.
08:25 eli: (b) you're doing it the hard way, instead: (define (random-list l) (list-ref l (random (length l))))
08:25 eli: (c) "random-list" is a bad name for that, since it chooses a random element it doesn't create a random list.
08:26 Girffe: (a) what do you use to specify a function, then? (if anything)
08:26 (quit) jeapostrophe: Ping timeout: 264 seconds
08:26 Girffe: (b) oh, I hadn't realized you could give arguments to (random), that's not as bad then
08:26 eli: Finally, I don't know about its popularity, but I doubt that *most* uses of `random'  are to choose from a list.
08:26 Girffe: (c) and yeah, I just made up the name in a second
08:26 eli: Re (a) -- juse use `random-list'.
08:27 eli: BTW, if the list is constant, you can also do this:
08:27 eli: rudybot: (define (choose . xs) (list-ref xs (random (length xs))))
08:27 rudybot: eli: your sandbox is ready
08:27 rudybot: eli: Done.

11:59 mithos28: stamourv: I needed a TR dev to help me figure out how best to delay evaluation of code from expansion time to typechecking time
12:00 mithos28: where expansion time is the local expansion of the module form, and not all of phase 1
12:00 stamourv: Ok.
12:00 stamourv: Do you still need help?
12:01 (join) ynniv
12:02 mithos28: I have a way, but I needed to add it to the typechecker
12:03 mithos28: I added a syntax property 'typechecker:external-check whose value is a procedure
12:03 mithos28: which is called with the form when it is discovered during typechecking time, and then typechecking procedes normally
12:04 mithos28: The original problem is to parse a type and make sure that it has no free variables, else error out
12:05 mithos28: but types cannot be parsed until typechecking time when aliases are added to the environment
12:05 mithos28: my solution also relies on semi-3D syntax
12:06 mithos28: as the syntax properties value is a procedure accessing the phase 1 environment
12:06 stamourv: That sounds sensible. Does it work?
12:07 mithos28: Yep, I was just wondering if there seemed like a better way than adding this whole new mechanism
12:09 stamourv: It sounds like a generally useful thing to have.
12:09 stamourv: We could use that to implement a `cast' form, like assert, but with types instead of predicates.
12:09 mithos28: already done
12:10 stamourv: Cool!
12:10 stamourv: People have been asking for that for a long time.
12:10 mithos28: I started with making a make-predicate form
