[Python-3000] Weird error message from bytes type

[Guido van Rossum]

Correct (I wasn't saying it was used on the lhs operand :-).

I find it important to use that API since anything that wants to
behave like a (small) int should be acceptable. Can you suggest a
better way to formulate the error from that API?
