`use super :: A` does not parse

[alexcrichton]

pub struct A;

mod test {
    use super :: A;
}

foo.rs:4:9: 4:14 error: found `super` in ident position

Can confirm this is still an issue with the latest rust

$ rustc hi.rs
hi.rs:4:13: 4:18 error: expected identifier, found keyword `super`
hi.rs:4         use super :: A;
                    ^~~~~
error: aborting due to previous error

$ rustc --version
rustc 1.0.0-nightly (1d00c545e 2015-01-30 19:56:34 +0000)

/cc @rust-lang/lang is this something we want to accept?

[pnkfelix]

one reason to hypothetically accept it: this form is sometimes produced by the pretty printer, I believe. :)

[nrc]

To be clear, this is not accepted solely because of the whitespace? If so, then I think we should fix this - having the parser rely on whitespace seems very bad (unless there is good reason, or for error recovery heuristics, etc.).

[alexcrichton]

@nrc I believe so, yes. For example this compiles (whereas the example in the issue does not)

pub struct A;

mod test {
    use super:: A;
}
