def append_to(element, to=None):
if to is None:
to = []
at the beginning of each function with default argument for set, list, or dict.

You can use mutable default arguments now with a new syntax:

This is only a Draft for now though
Oh wow! This would be great I really hope it’s accepted and implemented, makes a lot of sense!
