foo.bar: should expected :

[liigo]

use foo.bar; // expected one of `;` or `as`, found `.`

Should it expect a :?

Full example code:

mod foo {
    fn bar() {}
}

fn main() {
    use foo.bar; // expected one of `;` or `as`, found `.`
    bar();
}

It should expect ::, but it's lost from the expected set.
I't not an issue specific for use, but a symptom of a more general problem with expected token sets.
There's a long weekend ahead, I'll investigate.

Oh wait, this works on nightly, as expected (fixed in #33044, more specifically).
It means there are no problems with expected token sets.
