Test function can't have same name as a module in the same scope

[japaric]

STR

// test.rs
#[test]
fn mat() {}

mod mat {
    // NB Necessary to have a test here
    #[test]
    fn col() {}
}

Output

test.rs:1:1: 1:1 error: a type named `mat` has already been imported in this module
test.rs:1 // test.rs
          ^
error: aborting due to previous error

If you expand the file, you can see the collision:

$ rustc --pretty=expanded --test test.rs
// ...
pub mod __test_reexports {
    #[prelude_import]
    use std::prelude::*;
    pub use super::mat;  // <---
    pub use super::mat::__test_reexports as mat;  // <---
}
// ...

Version

This compiles today!

Hm, this is not actually fixed.
The name conflict still happens if --test is passed to rustc.
