3.5/2:  The simple call wrapper shall be derived from std::unary_function<cv 
T*, Ret > when pm is a pointer to
member function with cv-qualifier cv and taking no arguments, where Ret is 
pm's return type.

pointer to member function with cv-qualifier cv and taking one argument of 
type T1, where Ret is pm's return
type.
