[New-bugs-announce] [issue33129] Add kwarg-only option to dataclass

[Alan Du]

New submission from Alan  Du <ahd2125 at columbia.edu>:

I'd like to request a new option to the `dataclasses.dataclass` decorator to make the `__init__` keyword-only.

The two use-cases I have in mind are:

(1) Using as a dataclass big-bag-of-config. In this scenario, forcing the user to specify the keywords is a lot nicer than passing in a dozen positional parameters.

(2) Having kwarg-only parameters means that inheritance and default parameters play nicely with each other again instead of raising a TypeError.
