Give the inner field a name to prevent/discourage direct use, ensuring the invariant that it always has a valid value. This will be necessary for an upcoming commit that takes advantage of that invariant. I tried instead putting the enum into a module and controlling this with visibility, but I couldn't make it work correctly for enums defined within a function, as in the case of the doc tests.
