You may have to import them, or you have to prefix them with the module name -- whereas keyword args and True/False require neither. We could disallow order=True, eq=True. Or we could have the default being to generate __eq__, __ne__ and __hash__, and a flag to prevent these (since equality by object identity is probably less popular than equality by elementwise comparison). Perhaps: order: bool = False eq: bool = True and disallowing order=True, eq=False. -- --Guido van Rossum (python.org/~guido)
