I still don't understand what the point is of this complicated approach (adding
an argument to marshal.load()) compared to the simple and obvious approach
(making co_filename mutable).
Besides, the latter would let you code the recursive renaming algorithm in
Python, which is the whole point of importlib (rewriting most code in Python),
isn't it?
