This seems to call for a traits class (provided by compiler magic) that tells
whether objects are memcmp-comparable (although we might have to be careful to
ask it about the status of T[] instead of plain T, not sure about that). There
are already traits telling whether objects can be copied with memcpy, (I think)
whether objects can be initialized with bzero, etc.
