            AllEncompassingSet

a set that contains everything.

Ok, so this doesn't exist. Yes, I've read my Russell. You see, this is a restricted hack for a reason. And even the docstring is contradictory.

Sort-of. This now works for intersection and containing. Should this reject union? Also, unfortunately this only works as a left operand; I don't see how to override whatever set does with this as a right operand.

>>> s = AllEncompassingSet()
>>> s & set([1,2])
set([1, 2])
>>> "gooble" in s
True
>>> s in s
True
>>> s not in s
False
