Now I can't change cofilename from Python as it's a read-only attribute and thus can't match this functionality in importlib w/o creating some custom code to allow me to specify the cofilename somewhere Why can't we simply make cofilename a writable attribute instead of inventing some complicated API?

I thought of that question as well, but the later exchange between Guido and Brett made me realise that a lot more than the top level module code object is affected here - the adjustment also needs to be propagated to the code objects created by the module for functions and generators and so forth.

Cheers, Nick.
