Normally special methods use slots of the PyTypeObject struct. typeobject.c looks up all those methods on Python classes correctly. In the case of __enter__ and __exit__, the compiler generates bytecode to look them up, and that bytecode use PyObject_Getattr. -- Regards, Benjamin _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
