[docs] [issue23802] patch: __deepcopy__ memo dict argument usage

R. David Murray added the comment: I would rather say simply "The memo dictionary should be treated as an opaque object". On the other hand, I doubt we will ever change the structure of the memo dict, because I'm sure that somewhere out there there is code that is *not* treating it as opaque :) ---------- nosy: +r.david.murray _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue23802> _______________________________________
