00:51 mithos28: Havvy: What do you mean a 3d array?
00:52 mithos28: a vector of vector of vectors?
00:52 Havvy: Yes.
00:52 Havvy: Java's int[][][]

00:53 mithos28: Note that this concept is not idiomatic racket
00:55 Havvy: Well, how would you store the locations of things on a 3d discrete grid?
00:56 Havvy: Such as Final Fantasy Tactics battlefields.
00:56 mithos28: aren't those 2d for starters?
00:56 Havvy: The original tactics game is 3d.

02:46 Havvy wonders how to type annotate for*/list
02:46 mithos28: are you using typed/racket
02:47 Havvy: Yes.
02:48 mithos28: use for*/list: instead and do (for*/list: (Listof Number) ((x '(2 3 4)) (y '(4 5 6))) (+ x y))
02:54 Havvy: That's throwing an error for me.
02:55 Havvy: <unsaved editor>:3:26: for*/list:: expected the literal #:unless; expected the literal #:when; or expected optionally type-annotated identifier in: Listof
02:56 mithos28: Well thats because I missed the : after for*/list:

03:06 Havvy: Is there a bug on typed racket not having curryr with type information?

03:11 mithos28: ok, that was what I was going to suggest
03:14 (quit) dsantiago: Remote host closed the connection
03:14 Havvy: :/ My alternative to for/list* is 26 repetitive lines of code.
03:15 mithos28: what is it?
03:15 Havvy: Adjacent coordinates to a coordinate in 3d space.
03:15 mithos28: can you paste it somewhere?
03:16 Havvy: https://gist.github.com/e458480d5f9942135aea (and no, I didn't add type info yet)
03:18 mithos28: just do a (for*: …) which should work, and do an imperative update or do a for*/fold

09:50 torog: wait
09:50 torog: uh
09:50 torog: i got 5.2.1 too
