The second form should also work.Agreed. I have a bunch of pending changes for dataclasses. I'll add this.
This is bpo-32278.
I suggest two other fix-ups:
1) Let make_dataclass() pass through keyword arguments to _process_class(), so
that this will work:
Point = make_dataclass('Point', ['x', 'y', 'z'], order=True)
This is bpo-32279.
2) Change the default value for "hash" from "None" to "False". This might take a little effort because there is currently an oddity where setting hash=False causes it to be hashable. I'm pretty sure this wasn't intended ;-)
No time for this one yet. Soon! Eric. _______________________________________________ Python-Dev mailing list [email protected] https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
