Although I haven't done much about it. The problem is that it needs to return a new class, not just inject methods into the existing class you defined.

That's the current alternative, but namedtuples (unlike dataclasses) are slotted, which makes them more space-efficient and (slightly) faster.
When I use @dataclass(frozen=True), I manually add a __slots__ attribute. I presume this makes the resulting objects similar in size to NamedTuples, but I haven't done any measurements (and not sure how to measure this anyway).
I wonder: is it possible for @dataclass to have an option slots=True? And perhaps frozen=True should imply slots=True (would this cause any backwards compatibility problems?). _______________________________________________ Python-ideas mailing list -- email@example.com To unsubscribe send an email to firstname.lastname@example.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://email@example.com/message/OBFNLB...
