I'm don't see the point of this proposal. The fields of dataclasses are already mutable, so they can be updated just like any other object (no need for a special mechanism): a = InventoryItem(name='Widget', unit_price=37.25, quantity_on_hand=10) a.quantity_on_hand -= 1 # Sold one a.unit_price *= 0.90 # Ten percent off sale Also, it's not hard to directly take data from one instance to another: a.name = master_catalog.name a.unit_price = master_catalog.unit_price ---------- nosy: +rhettinger _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35761> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
