Sorry, I don't know how I communicated that I was trying to have one class be a set of fields and also the enum for one of its own fields. I'm really just wanting to have each member of the enum be an instance of a frozen dataclass. If an of the dataclass fields were of an enum type, then it would presumably not be for the same enum. In my example, none of the fields of the dataclass contains an enum. One contains a string, and the other contains an int. ___ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/KWL2FXQ2FKRMGBAB5PMR3GIRAQBC6CLR/ Code of Conduct: http://python.org/psf/codeofconduct/

I've seen this thread, and also wondered why anyone could EVER want a dataclass that is an enum. Nothing I've seen in the thread gives me any hint about that, really.

It is usually considered a code smell to have a class that is two or more things. This seems to be what you are trying to do. How can one class be a set of fields and also the enum for one of its own fields? I do not understand why this is resonable.
