12:31 jonrafkind: whats that
12:31 stamourv: It's a tool that help you get better paralellism with futures.
12:32 stamourv: It tells you what your futures are blocking on, and shows a timeline of the work.
12:32 stamourv: Give it a try!
12:32 jonrafkind: have you tried it?

12:33 jonrafkind: how do I invoke it

18:41 Nisstyre: I'm writing a parser and I don't want to repeat that particular bit of code a bunch of times
18:41 Nisstyre: but none of those variables are in the same scope as the macro
18:42 asumu: Nisstyre: this doesn't sound like you want unhygienic macros, but syntax parameters.
18:43 Nisstyre: asumu: how would that solve my problem?
18:43 asumu: rudybot: (require mzlib/transcr)

18:43 rudybot: asumu: error: open-output-file: `write' access denied for test
18:43 asumu: Nisstyre: Well, it's hard to tell without more context, but the `continue-parsing` is part of another macro right?
18:44 Nisstyre: asumu: no
18:44 Nisstyre: it's a procedure
18:44 asumu: What are parens, next, and previous then? Bindings you have in the body of some function?
18:44 Nisstyre: I can paste my code if you want, it's kind of messy
18:44 Nisstyre: yes
18:44 asumu: I just don't think you want an unhygienic macro here. It just makes your code harder to reason about.
18:45 asumu: Why not just bind a new procedure here?
18:45 Nisstyre: parens is just a count of how many left and right parentheses there are, it's a struct
18:45 Nisstyre: asumu: I suppose I could do that, with let
18:45 asumu: (define (continue-parsing) (parse parens next previous))
18:45 Nisstyre: but then I have mutually recursive functions
18:45 Nisstyre: which also call that
18:45 Nisstyre: I suppose that would work
18:45 Nisstyre: I guess I never thought of doing that, derp
18:45 (quit) josdeha_rt: Remote host closed the connection
18:46 Nisstyre: asumu: wrapped in a lambda, though right?
18:46 Nisstyre: I'd rather not use define in a procedure
18:46 asumu: Well, that's a stylistic choice. It's up to you.
18:46 Nisstyre: okay, thanks for the advice
18:46 asumu: I usually use internal definitions (just my habit).
18:46 asumu: No problem.
18:53 Nisstyre: asumu: that works fine for my main procedure, but it's actually mutually recursive, so it won't extend to the other procedures...
18:54 Nisstyre: I suppose I could just have it for that one and put up with the long procedure call in the others
18:56 Nisstyre: I think this is a fairly legitimate use of unhygienic macros personally, because I'm not expecting anyone else to use the macro apart from in this module
18:57 asumu: Generally, I don't think you should use macros to do something that a procedure can do.
18:57 asumu: Especially because all you're doing here is saving a few lines.
18:58 Nisstyre: fair enough

23:48 eli: asumu: And re the documentation question -- try a search for "L:" -- it might be what you're looking for.
23:50 asumu: eli: it's definitely implementable, but the question is if it's necessary if it's only used internally.
23:50 asumu: Since nobody who requires racket/promise can get at it. Only people in the core who use racket/private/promise.
