Code objects are immutable, and marshal'able (a .pyc file is basically just a magic-numbered, time-stamped, marshalled code object for the module). Marshal can't marshal arbitrary Python objects. Functions are mutable, and constructed at run-time, so can reference arbitrary Python objects. Since you want default values to possibly be user-defined Python objects, the defaults are on the function, not the code object. --Ned. -- https://mail.python.org/mailman/listinfo/python-list
