I'm curious about this. What do you mean? Python 3 has unbound methods, they're just the original, unwrapped function: py> class K: ... def method(self, arg): ... pass ... py> K.method <function K.method at 0xb7cbd6a4> The only(?) functional difference between unbound methods in Python 2 versus 3 is that in Python 2 they automatically do a type-check that `self` is an instance of the class. -- Steve _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
