Greetings everyone. I hope you all had a great Christmas holiday. 8-)

I am posting this Enum (named number) class to this list for possible feedback. It can be used as a regular integer but when printed (stringified) it yeilds its name. The hash also makes named numbers with the same integer value into unique dictionary keys. That is the part I am not sure about... Comments appreciated.

class Enum(int): slots = ("_name") def new(cls, val, name): v = int.new(cls, val) v._name = str(name) return v def str(self): return self._name def repr(self): return "%s(%d, %r)" % (self.class.name, self,self._name) def hash(self): return int.hash(self) + hash(self._name)
