[issue41517] Able to subclass enum with members by using multiple inheritance

[Steven D'Aprano]

Steven D'Aprano <steve+python at pearwood.info> added the comment:

The documentation says:

"Allowing subclassing of enums that define members would lead to a violation of some important invariants of types and instances."

but it isn't clear what those invariants are, or why it is more of a problem for enums than any other subclassing situation. Could the docs be updated to explain why it is prohibited?
