Well, by mucking with the new module, you can get two functions with
the same code object.

Also it's possible to execute a code object without an associated
function - like the top-level of a module for example.

I think you can probably come up with something that will work most of
the time, but not all the time.  Whether that's good enough for you is
up to you...
