[swift-evolution] Dotless case names in switch cases

[肇鑫]

let Foo:SomeEnum = .Bar
let Bar:SomeEnum = .Foo

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.")
        }
    }
}

above code works in current Swift. It will not work after your changes.
