| * libraries in the super-interface chain, since a legacy library is permitted |
| * to override otherwise incompatible signatures for a method. |

| * @description Check that if opted-in class implements two classes with some |
| * method (one is legacy), compile time error is thrown if parent legacy method |
| * parameter is of any legacy type and child opted-in method parameter is |
| * [Never]. |
