Add sugar to simplify mutable function arguments #3488
Description
While it's pretty easy to write a function that makes an argument mutable:
fn foo(x: ~int) {
let x = move x;
...
}
It'd be nice to save a line here and there to add some sugar to express an argument is directly mutable, with something like:
fn foo(mut x: ~int) { ... }

I've stubbed my toe on this as well.

I started tagging some of the places in the code where this would be useful with

Can places with FIXME be fixed, or does that require a snapshot?
catamorphism commentedon Jan 23, 2013
@sanxiyn Yes, that will require a snapshot, because it has to be possible to compile the libraries with the stage0 compiler (the existing snapshot). But we are going to make a snapshot soon.
