I don't like your solution, this class was already slow enough. Don't
use unbound methods with this class :-)
Maybe there's a (better) solution to your problem: to make Heap a
function (or classmethod) that return sone of two possibile objects
created by one of two different classes that have different methods...

Beside that, I think __eq__ method needs more tests, because comparing
a Heap with key against another Heap without key may give some
problems...

I'll think about such problems/things.
