Parameterized + ABC?

Param
1

I’m working on a package and trying to implement an easy interface for extensibility using abstract classes and parameterizing the classes. However, those two don’t play well together when used as superclasses together.

class BaseRAG(ABC, Parameterized):
    some_name = param.String(default='Default Name')
    @abstractmethod
    def create_corpus(self):
        pass

TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases

Thanks to Mr. Claude Opus, this seems to work(at least, for now):

from abc import ABCMeta
from param import Parameterized

class ParameterizedABCMeta(ABCMeta, type(Parameterized)):
    pass

class BaseRAG(Parameterized, metaclass=ParameterizedABCMeta):
    some_name = param.String(default='Default Name')
    @abstractmethod
    def create_corpus(self):
        pass

Would this be the best path forward, or is there something I’m missing?
