__cmp__ no longer exists in Python 3, so this solution could only work in
Python 2.
Here's a version using rich comparisons:
class Greatest:
__eq__ = __le__ = lambda self, other: isinstance(other, type(self))
__ne__ = __gt__ = lambda self, othr: not isinstance(othr, type(self))
__lt__ = lambda self, other: False
__ge__ = lambda self, other: True
__hash__ = lambda self: 42
