[issue9930] Incorrect semantics of __radd__ method for builtin types

Georg Brandl <georg at python.org> added the comment:
This is indeed weird. PyNumber_Add ends up calling compare_add with the float as its first argument, which is impossible to do from Python. And the wrap_binaryfunc_r check for subtypes means that compare.__radd__ claims it doesn't support floats either. So from Python, it's impossible to add floats and complex numbers via __special__ methods :)
Maybe Mark wants to shed some light?
