auto merge of #6432 : thomaslee/rust/issue-4202-02, r=catamorphism
My earlier fix for #4202 would not work correctly if the trait being exported was a top-level item relative to the module from which it was being exported. An example that would not work correctly with the original patch: // foo.rs pub use Foo = self::Bar; pub trait Bar { pub fn bar() -> Self; } impl Bar for int { pub fn bar() -> int { 42 } } // bar.rs fn main() { foo::Foo::bar() } This is now supported. I believe this change will allow the GenericPath trait to be exported from core::path as Path in such a manner, which should allow #5389 to move forward.
