You realize, of course, that it's possible to add labels to an enum type
today. (Removing them is another story.)
You haven't explained exactly what you have in mind that is going to be
able to duplicate the advantages of the current enum implementation
without its disadvantages, so it's hard to evaluate this proposal.
