The question remains, though, how far we should go to sacrifice the objective technical benefits of using scoped enums for a (subjective) notion of readability? Maybe have a second look at my suggestion to use scoped enums, but then break the scope with (the equivalent of) `using enum`? I think that might be a good compromise.
