| * @assertion Let [G] be a generic class or parameterized type alias with formal |
| * type parameter declarations [F1] .. [Fk] containing formal type parameters |
| * [X1] .. [Xk] and bounds [B1] .. [Bk]. We say that the formal type parameter |
| * [Xj] has a simple bound when one of the following requirements is satisfied: |
| * [Bj] is omitted. |
| * [Bj] is included, but does not contain any of [X1] .. [Xk]. If [Bj] contains |
| * a type [T] on the form qualified (for instance, [C] or [p.D]) which denotes a |
| * generic class or parameterized type alias [G1] (that is, [T] is a raw type), |
| * every type argument of [G1] has a simple bound. |
| * @description Checks that simple bounds of non-function type alias are correct |
| * for [A<X extends List<List>>], [B<X extends Map<Map, Map>>] |
