hi,
i learning rust-lang and i need some help of you.
In following example, test0() and test1() don't compile.
How should I write test0 () and test1() correctly?
(sorry my bad english).
saludos

[fedel@fedel ~/src/rust-0.1]$ cat ask1.rs
use std;
fn naux(n : int) -> int { n + 1 }
fn test0(l : [int]) -> [int] {
ret vec::map(l, naux);
}
fn test1(l : [int]) -> [int] {
let baux = fn@(n : int) -> int { n + 1 };
ret vec::map(l, baux);
}
fn test3(l : [int]) -> [int] {
ret vec::map(l, {|n| n + 1});
}
fn main(args: [str]) {
test0([0,1,2,3,4]);
test1([0,1,2,3,4]);
test3([0,1,2,3,4]);
}
