In this case, wouldn't it be nicer to "decorate" those attributes that
are meant to be enum values? I think having to use the class keyword to
define something that really doesn't behave like an ordinary class is
pretty confusing, and the following syntax would be a lot easier to
understand at first sight:
class Insect(enum.Enum):
ant = enum.EnumValue(1)
bee = enum.EnumValue(2)
@classmethod
def spam(cls, args):
pass
def ham(self, args):
pass
Obviously, EnumValue() would automatically assign a suitable number.
Best,
