+1 for ".values" instead of just ".count". Really handy feature that Java has. In Java it returns a set not an array which is great for representing status. In C you would use a bit field, but an enum set is better.

I don't need ".count" on its own, but ".values" ... well, I have a whole load of enums in my current projects with a ".values" I had to hardcode myself. I would love to get that for free.
