Easily fixed:



class Greatest (object):
    def __cmp__ (self, other):
        if isinstance (other, Greatest):
            return 0
        return 1
        
    def __hash__ (self):
        return id (Greatest)
        
class Least (object):
    def __cmp__ (self, other):
        if isinstance (other, Least):
            return 0
        return -1
        
    def __hash__ (self):
        return id (Least)
