I am finding that it would be useful to be able to define a dataclass that is an abstract base class and define some of its field as abstract.

As I am typing this, I realize that I could presumably write some code to implement what I'm asking for. Maybe it is a good enough idea to make part of the standard API in any case though? I'm thinking that a field would be made abstract by passing `abstract=True` as an argument to `dataclasses.field()`.

You're better off discussing this on discuss.python.org as this mailing list is basically dead.

And when you do post over there, please provide an example. It's not clear what would happen in the generated code if abstract=True.
