I don't think that every type that supports equality comparison should support order comparison. I think that if there's no meaningful comparison (whether equality or order), an exception should be raised.

def date_range(start=None, end=None): if start == None: start = datetime.date.today() if end == None: end = datetime.date.today() return end - start
Are you saying the "if" statements will raise TypeError if start or end are dates? That would be a sad day for Python. Perhaps you're saying that there is a "meaningful comparison" between None and anything else, but please clarify if so.
