Serhiy Storchaka <storchaka+cpyt...@gmail.com> added the comment:
Why deepcopy is used at all? It is a very specific feature which should not be
used by default. If you want to make a deep copy of fields, you can call
copy.deepcopy() explicitly.
copy.deepcopy(dataclasses.astuple(obj))
or
dataclasses.astuple(copy.deepcopy(obj))
