But aren't all classes callable?
An enum of classes would be seriously weird as well, I think.
I don't think iscallable will work, since that descriptors like
staticmethod and classmethod aren't callable. Nor are properties.
I think a solution may be an explicit decorator that tells the
metaclass not to skip the object into an enum value:
class Insect(enum.Enum):
ant = 1
bee = 2
@enum.skip
@classmethod
def spam(cls, args):
pass
assert isinstance(Insect.spam, classmethod)
One side effect of this is that now you can (ab)use the decorator
to have regular data attributes. Whether that counts as a good
thing or a bad thing, I leave up to others to decide...
