Comment:
I noticed a bug while looking at the relevant code in __cmp__:
{{{
if not isinstance(right, Set_object):
return cmp(type(right), type(Set_object))
return cmp(self.__object, right.__object)
}}}
Notice that the first compare is totally backwards! Interestingly,
fixing this does fix the above bug. Patch attached.
