This only makes sense to me if it's then illegal to declare any variables
of that enum type, because if you're looking to use an enum to give a
list of possible values rather than enumerating the exact list of values,
why would you be marking _any_ variable as being of that enum type?
I don't understand that contention. "final" clarifies that the set of
values in the enumeration is closed.
I take issue with the idea that it makes sense to have any variables of an
enum type that isn't one of the values enumerated in the enum.
I explained the possible situations in the original post of this thread.
E.g. one may be unable to enumerate all user IDs, but may be compelled
to enumerate a few remarkable ones and ascribe user IDs a separate type.
