Ignoring that 'new' is not in Python 3.x (luckily 'types' is), I want a proper solution that doesn't require reconstructing every code object that I happen to import. Practicality beats purity.  ;-)  (Especially if it allows importlib to run on older Pythons.)

I don't care about making importlib run on older versions of Python before 3.1. And this is a minor enough thing that I am not worried about missing in Python 3.1.

Also, surely you're not worried about performance here?

I do care about performance to an extent, but that is not the primary motivating factor to wanting to go with the marshal API change.
