I would prefer for it to be a member, so that we could take advantage of my
operators.h library ;)

My instinct is that it should be a member. I know it might seem draconian,
but I don't like the idea of even allowing a specialization. I would prefer
that users be forced to define a functor for use where a different
comparison is desired. Some people prefer as much flexibility as possible. I
prefer lots of flexibility, but no more than neccessary. The flexibility to
specialize op== in this way, it seems, can only cause confusing code with no
significant benefit.
