Description
If a trait declares a method that has the same name as a method from its trait hierarchy, then both methods can only be called via UFCS. It's also confusing. As such, clippy should lint against it.
trait Base {
fn method() {}
}
trait Subtrait : Base {
//~ warning: method has same name as Base::method.
fn method() {}
}
