Description
This compiles after full NLL (>= 1.63) but it shouldn't:
trait Trait {
type Ty;
}
impl Trait for &'static () {
type Ty = ();
}
fn extend<'a>() {
None::<<&'a () as Trait>::Ty>;
}
HIR typeck unconditionally normalizes user-provided types modulo regions, so it's not NLL's fault this time :)
