Use statements do not shadow previous items

[brson]

This is allowed but doesn't do what you might expect.

mod foo {
    pub fn bar() -> int { 10 }
}

mod baz {
    pub fn bar() -> int { 20 }
}

use foo = baz;

fn main() {
    // This will fail - calling into mod foo, not mod baz
    assert foo::bar() == 20;
}

It used to be that 'use' statements only came before items and the items shadowed the use statements. Now they may appear alongside items, but the items still shadow the use statements, regardless of order.

Proposal: make use statements only work before items. Bringing this up in next meeting.

[brson]

agreed, but for all view items. that was the original behavior and I never knew why it was changed

[brson]

oh I guess what I wrote was a little redundant. didn't realize this was my issue

[thestinger]

use statements now have to precede items, closing
