From the discussion of issue 643841: >>> class Demo: ... def __index__(self): ... return 1 ... >>> a = Demo() >>> b = weakref.proxy(a) >>> operator.index(a) 1 >>> operator.index(b) Traceback (most recent call last): File "", line 1, in TypeError: 'weakproxy' object cannot be interpreted as an index The weakref proxy types need to be updated to delegate 2.5's new tp_index slot.

Marking as easy - it should be possible to just look at what the code in Objects\weakref.c is already doing for slots like tp_len and tp_int and do the same thing for tp_index.

Fixed in r63500, together with the floor/truediv slots.
