The hash method of A's class, ie. A.__class__.__hash__, usually
type.__hash__.

Hmmm. I think I get your point. hash and cmp and so on should call
A.__class__.hash(A) to be generic enough.   

It's still confusing.. =) And how should I resolve this issue with my
Dummy class? (it's ok for the Dummy class itself to be a Dummy, but it
didn't work well to make Dummy = Dummy())
