chained import error message unhelpful

[metajack]

Currently doing:

use vectors = core::vec;
use vectors::raw;

fails with "error: unresolved import". It would be much better if this gave the real reason. Perhaps "error: chained imports are not allowed".

The error is still not too helpful.

Visited for triage, still valid but low-priority.

This compiles now. I'll add a test.

As @huonw pointed out, I was wrong about the test -- actually, this is the test for this bug, which still yields an unhelpful error (one that doesn't mention chained imports):

mod foo {
    use vectors = std::vec;
    use vectors::raw;

    pub fn whatever() {
        use vectors::from_elem;
        let _ = from_elem(1, 5);
    }
}

fn main() {
    foo::whatever();
}

With that said, I don't think this is a milestone blocker.

The original issue had nothing to do with chained imports, but the fact that it needed to be a use self::vectors::raw;, which works today. Closing.
