[swift-evolution] Dotless case names in switch cases

[Jens Persson]

enum SomeEnum {
    case Foo
    case Bar
    func demoDotAndNoDot() {
        switch self {
        case .Foo: print("This has the usual dot before the case name.")
        case Bar: print("This has no dot, which is ok, at least in this
particular context.")
        }
    }
}

I'm just throwing this out in case someone should feel like writing a
formal proposal to remove the dotless form.

I'd be ok with removing it since it only works in some specific contexts.
