| /** |
| * @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 are correct for [typedef] with |
| * [typedef] parameter (not used). |
| * Note that G2<T1> == G2<T2> == void Function() for all types T1 and T2. So as |
| * long as you have F<G2<...>> it doesn't matter what ... stands for, it's |
| * always just the same type. |
