Brett Cannon added the comment:
I think operator.index() should be brought to be inline with PyNumber_Index():
- If the argument is a subclass of int then return it.
- Otherwise call type(obj).__index__(obj)
- If not an int, raise TypeError
- If not a direct int, raise a DeprecationWarning

Otherwise it's the nt.listdir() comparison that's failing. Probably should
