Your supposition that Foo.foo is not considered callable by Python is false, as Chris already demonstrated, and I don't see where anybody here has stated otherwise. What Peter wrote was that "a staticmethod instance is not a callable object", which is absolutely correct, and these two facts are consistent because Foo.foo is not a staticmethod instance (Foo.__dict__['foo'] on the other hand *is* a staticmethod instance and *is not* callable, and Foo.__dict__['foo']() will correspondingly raise a TypeError). -- https://mail.python.org/mailman/listinfo/python-list
