Of course, speaking of a rewrite, PyPy does the "right thing" in these two areas. Won't happen to CPython, though. There are too much backward-compatibility issues with the PyTypeObject structure; I think we're doomed with patching the bugs as they show up. Looking up in the language reference, I see no mention of NotImplemented in the page about __add__, __radd__, etc. I guess it's a documentation bug as well, isn't it? The current code base tries to implement the following behavior: Returning NotImplemented from any of the binary special methods (__xxx__, __rxxx__, __ixxx__) makes Python proceed as if the method was not defined in the first place. If we agree on this, I could propose a doc fix, a test, and appropriate bug fixes.
