Evolution idea: implicit return in single-line switch cases

[orchetect (Stef)]

I noticed a very similar request in that thread here: Control Flow Expressions - #13 by Cameron_Knight

@Cameron_Knight

let paint.finish = returning switch paint.color {
    case .Black:
        .Matte
    case .White:
        .Eggshell
    default:
        .Gloss
}

One other suggestion there was to use a dictionary but then that introduces Optional semantics to what is often a finite case selection and is still uncomfortable in ad-hoc situations where you want to define the switch cases in context.
