Comment (by debanshuk): Replying to [ticket:26287 kezabelle]: > As far as I can tell, the implementation can't just be > {{{ > __radd__ = new_method_proxy(operator.radd) > }}} > because that doesn't exist, which is rubbish. > {{{ > __radd__ = new_method_proxy(operator.attrgetter("__radd__")) > }}} > also won't work because types may not have that attr, and attrgetter doesn't supress the exception (correctly) Wouldn't the following code work? {{{ __add__ = new_method_proxy(operator.add) __radd__ = new_method_proxy(lambda a, b: operator.add(b, a)) }}} I have tested this and it seems to work as excepted. -- Ticket URL: <https://code.djangoproject.com/ticket/26287#comment:5> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
