What seems an internal implementation issue to you is a philosophical issue
to others. You dismiss it at your peril (i.e. a waste of your time). Binary
operators in Python are always implemented by letting one or the other
argument provide the implementation, never by having the language pick an
implementation (not even a default implementation). What you see in the C
code that might seem to contradict this is either an optimization or an
ancient artifact, not to be copied.

Good luck. I'm checking out of this thread until a PEP is deemed ready for
review.
