Today Rust has a new closure syntax:
let two_three_four = [1, 2, 3].map( |i| i + 1 );
That's pretty great. Especially since it runs entirely in stack
allocations. Whee.
let x = cat, y = dog, z = turnip;
let party = |w, move x, copy y| w + x + y + z;
Argument and return type annotations are optional.
let party = |x: Cat, y: Dog| -> Octopus x + y;
These are some remarkable parties.
Empty argument lists can be omitted in both `for` and `do`
do spawn {
...
}
Yep!
Cool. Looks like it'll handle a lot of control abstractions without
looking strange; I was a doubter but now I'm a believer. Bravo!
