I'm not sure I understand. There's a single type of "code object" and it's
PyCodeObject. Making the attribute writable (from Python code) at that level
should be sufficient.
(then of course the recursive machinery needed to mutate all code objects
created in a module may be slightly inefficient if written in Python, but at
least it's possible to write it)
