It makes sense to subclass the type directly if I'm not messing with
result or bind values. This works:
class StringEnum(types.Enum):
def __init__(self, *args, **kwargs):
super(StringEnum, self).__init__(*args, native_enum=False,
**kwargs)
self.length = 255
I'm still curious why the TypeDecorator I pasted previously doesn't
work though. The superconstructor does the self.impl =
self.__class__.impl(...) anyway so I figured this was the better
approach than calling self.impl = Enum(...).
