[swift-evolution] Ad hoc enums / options

[Vladimir.S]

IMO interesting idea.. We have ad hoc structs as tuples and it seems like 
ad-hoc enums also could be helpful when we don't need a separate class for 
using in limited scope.

I also can see advantage to use such anonymous enum type in code:

var codePath : (.one | .two | .three) = .one

...

switch codePath {
   case .one : ...
   case .two : ...
   case .three : ...
}

IMO very clean and expressive code and I like the proposed syntax.
So I'd like to have such in Swift
