Allow me to repeat:

"The thing is, either this suffers from == behaving differently than AAs, or 
you've made opEquals superfluous by defining it to be opCmp==0. The latter is a 
mistake, as Andrei has pointed out, as opCmp may not have a concept of equality, 
and opEquals may not have a concept of ordering."

This is the crux of the matter.
