Thanks Eric and Ivan. You're both very responsive. I appreciate the enormous efforts you're putting in to getting this right. 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) 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 ;-) Raymond _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
