Given that @dataclass is a decorator, and otherwise you're just defining a class, some concerns: 1. Such proposed syntax would require a change to the language specification. 2. It would seem that / and * in a class not decorated with @dataclass would be of no other utility. Paul On Thu, 2021-03-11 at 10:08 -0500, Ricky Teachey wrote:

This might be a bit of an extreme step to take, but has new syntax for this ever been discussed? Here I am using the same indicator for keyword arguments as in a function signature, hanging on a line by itself:
...
@dataclasses.dataclass class Comparator: / # args become positional after this line a: Any b: Any * # args become kwd args after this line key: Optional[Callable[whatever]] = None
Actually, the '/' indicates that names /before/ it are positional only.

Yes you're of course correct! Sorry!
So the corrected version would be:
@dataclasses.dataclass class Comparator: a: Any b: Any / # args before this line positional only * # args become kwd args after this line key: Optional[Callable[whatever]] = None
