Just one. The empty interval is a singleton and I want it to be smaller than any other interval. UTC_ZERO = datetime.datetime.utcfromtimestamp(0) EMPTY_INTERVAL = Interval(UTC_ZERO, UTC_ZERO) # TODO: how generalize this for any ordered type? Probably I could use Interval(None, None), and refactor my code. The other problem would be __str__ and formatting, but that is easy to generalize. > > Personally I would use & | instead of * + -- Python is not Pascal ;) Operators changed to what you have suggested.
