One thing you can say about dataclasses is that they provide a way to handle all parameters, mutable and immutable.
Really? I did not know that. Interesting.
Definitely an issue of dataclasses being special, though, and not attributable to the syntax used to make a dataclass.
Absolutely -- my point is that if you want to auto-assign all parameters, then a dataclass is a good way to do it. If you need to write handling code for most parameters, then the current do-it-by-hand approach is fine. A new syntax would help most when you need to write custom code for a few parameters, but auto-assign the rest. I brought up mutable defaults, as they would require custom code, making the auto-assignment a tad less useful. But perhaps if the recent ideas for late-bound parameters ever bears fruit, then combining that with auto-assigning would increase the usefulness of both features. -CHB
