[swift-evolution] [Idea] Find alternatives to `switch self`

[Kevin Lundberg]

This can be done today with no syntax changes (you'd have to return
optional or handle the nil case though):







  var description: String? {
    return [
      .Hearts: "♥️",
      .Spades: "♠️",
      .Diamonds: "♦️",
      .Clubs: "♣️"
    ][self]
  }
