That satisfies my concern. This gives an author the means to provide two
names for a single value, and a way to choose which one is canonical. It's
easy to imagine some corner cases related to persisting those values and
then retrieving them with a later enum definition that changes the
canonical name, but if you store raw values or names it should be easy
enough to work around such things.
