Good catch. It technically needs to check the lower bound, too. In
theory, if somebody wanted to add an enum value that is negative, you'd
use a signed cast and check against both 0 and ARRAY_SIZE(). In
practice, that is nonsense for this case, and using an unsigned type
means that any negative values become large, and the check catches them.
