Names of function types shouldn't allow parameter names

[brson]

let fn(int x) a = f is a valid declaration but the x is useless.

I think this is intentional -- you can optionally include them, as documentation, but don't have to.

[eholk]

I think they might be required for right now... at least, I seem to recall having problems with leaving them out before.

[marijnh]

I'm pretty sure they are optional currently. See https://github.com/graydon/rust/blob/master/src/comp/syntax/parse/parser.rs#L256

[eholk]

At least in native modules, this doesn't seem to work. I'm trying to make this compile:

native "rust" mod rustrt {
    fn set_min_stack(uint);
}

It fails with "error: expecting ident."

[marijnh]

Ah, that's a native function item, not a type. Yes, they seem to be required there. I think Graydon considered them desirable for documentation there. I actually agree it seems sane to require them.

[msullivan]

Yeah, I vote for keeping them allowed.

[msullivan]

I think consensus is WONTFIX.
