[issue39805] Copying functions doesn't actually copy them

[Serhiy Storchaka]

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:

It is by design. Functions and types are pickled by name. The copy module uses the pickling protocol and only use different methods for performance or for non-pickleable objects. Changing this will break existing code.
