impl Trait for module yields weird error message

[jdm]

mod a {
}

trait A {
}

impl A for a {
}

fn main() {
}

/tmp/foo.rs:7:11: 7:12 error: found value name used as a type: def_mod({crate: 0, node: 1})
/tmp/foo.rs:7 impl A for a {
                         ^

We could do better here.

This looks like it can be closed.

Perhaps this issue should be closed, as it now gives a much more useful error:

8763.rs:7:12: 7:13 error: found module name used as a type: mod a::a (id=4)
8763.rs:7 impl A for a {
                     ^
