Tuples are read-only.

Ah, of course. Good point. I tend to write things in an immutable style, so I don't usually pay attention to this.

I see immutability as a feature.

There are uses cases for mutability, but it should be opt-in, not opt-out. So I'm not loving the fact that "frozen" (the mutability param for data classes) defaults to False.

I agree, which is part of the reason I think I'd be inclined to derive from NamedTuple and forego data classes.

Python is very much not immutable by default, it'd be weird to subvert it in a specific case.

Also, AFAIK you cannot add methods to NamedTuple, making it much less flexible than data classes.

One of the examples in the documentation uses a method. https://docs.python.org/3/library/typing.html#typing.NamedTu...

Yeah, you're right. You just cannot overwrite __init__:
