| 15 | // | (ignoring the top-level cv-qualifiers), or | |
| 16 | // | * the handler is of type cv T or cv T& and T is an unambiguous base | |
| 17 | // \ class of E, or / |
| 18 | // * the handler is of type cv1 T* cv2 and E is a pointer type that can |
| 19 | // be converted to the type of the handler by either or both of |
| 20 | // o a standard pointer conversion (4.10 [conv.ptr]) not involving |
