//  \     class of E, or                                                       /
//     *  the handler is of type cv1 T* cv2 and E is a pointer type that can

//          o  a standard pointer conversion (4.10 [conv.ptr]) not involving
//             conversions to private or protected or ambiguous classes
//          o  a qualification conversion
