Sure, Andrei makes a valid point .. for a minority of cases. The majority case will be that opEquals and opCmp==0 will agree.

You've agreed with my point, then, that autogenerating opEquals as memberwise equality (not opCmp==0) if one is not supplied will be correct unless the user code is already broken.
