You mean this? class BehaviorMixin: # bla bla class MyBehavingIntEnum(int, BehaviorMixin, Enum): foo = 1 bar = 2

Yes, but without the need for multiple inheritance and separate mixins ;-) Especially if the behaviour is enum-specific, e.g.:

class IETFStatusCode(IntEnum):

@classmethod
def from_statusline(cls, line):
    return cls(int(line.split()[0]))

class HTTPStatusCode(IETFStatusCode): NOT_FOUND = 404

class SIPStatusCode(IETFStatusCode): RINGING = 180

Regards

Antoine.
