But of course it doesn't just lookup C.__call__, because it has to bind the method to the instance before calling it, which means invoking the descriptor protocol. The actual lookup is more like: type(a).__dict__['__call__'].__get__(a, type(a)) -- https://mail.python.org/mailman/listinfo/python-list
