[swift-evolution] ternary operator ?: suggestion

[thorsten at portableinnovations.de]

I would prefer the expression to match the statement. The only difference would be that all parts that were statements now have to be expressions.

Therefore the switch-expression should simply look like follows:

let thisColor = switch thatColor {
         case .Red: .Green // must be an expression
         default: .Yellow      // must be an expression
     }

No returns needed in the case clauses.
Formatting this as a one-liner would just require adding semicolons (though I wouldn't recommend this).
