Spurious dead_code warning when type is only used in path

[apasel422]

foo.rs:

trait Bar {
    fn bar() {}
}

enum Foo {}

impl Bar for Foo {}

fn main() {
    Foo::bar();
}

Warning:

By the way, the warning goes away if you explicitly specify the trait who's static method you are calling, like so:

<Foo as Bar>::bar();
