Adjust self-type check to require equality When we encounter `SomeType::<X>::foo`, `self_ty` is `SomeType<X>` and the method is defined in an impl on `SomeType<A>`. Previously, we required simply that `self_ty <: impl_ty`, but this is too lax: we should require equality in order to use the method. This was found as part of unrelated work on never type stabilization, but also fixes one of the wf test cases. |
