That's a tough one. Because C.d is not set to a descriptor at type creation time (it's set to a Field object), the __set_name__ behavior is never invoked. It's when the @dataclass decorator is called that C.d is set to D().

https://docs.python.org/3/reference/datamodel.html#creating-the-class-object

I'm not sure it's possible to work around this without duplicating some of the type creation code, and even then I'm not convinced it's doable.
