But you know from the outset that these functions will eventually become generic, so why can't they be defined as some callable object that can have its insides switched, if you're on a Python whose normal function objects don't allow that?

Well, phrased that way, it sounds like a justification for treating it as a porting strategy for such Pythons. The library could just use a "copy_code(srcfunc, dstfunc)" function that's implemented differently on different Pythons.
