If planets want to have attributes and behaviors, let them be normal classes. If they want a PlanetId *enum member*, that's OK, but there's no need to intermix the two. Besides, did we not agree that the only acceptable *members* for enums are going to be descriptors? In the above, mass & radius are not descriptors. Eli
