@adriangb I added a test that xfails. The internals of stdlib dataclasses does not assign default factory attributes to the class instance (meaning the warning isnt triggered in this case). It also means that you are right, the default factory is not propagated to the resulting
FieldInfo
instance (because thedataclass.Field
isnt assigned toBase
but ratherBase.__dataclass_fields__

The inheritance works fine if you provide a value, so for my usecase this isn't an important feature to support. I added a test for what we need to work, though.
