[swift-evolution] Pre-proposal: CaseEnumerable protocol (derived collection of enum cases)

[davesweeris at mac.com]

I am NOT saying “here’s the answer”, but I put something up on my github that does some of this: https://github.com/TheOtherDave/EnumEnhancer

Again, not saying that’s how we should do it or anything, but if anyone thinks it’d be useful until the “official” enhancements come out, help yourself. There’ll still be boilerplate, but it makes some attempt to keep things correct.
