Why can't we simply make co_filename 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.
Even if it is not necessary or sufficient it still sounds like a useful
change. When writing tools that generate modules or manipulate code
objects these read-only attributes are a great nuisance.
