| /// @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 |

| /// [Bj] is omitted. |
| /// [Bj] is included, but does not contain any of [X1] .. [Xk]. If [Bj] contains |
