enum Genre {
    case fiction
    case scifi
    case nonFiction
    case history
    case science
    case medical
    case other(name: String) //Associated value

    var isSciencey: Bool {
        switch self {
            case .scifi, .science, .medical: return true
            default: return false
        }
    }
}
//The code above lets us do this:
let isSciencey = someGenre.isSciencey

//Instead of this:
let isSciencey = someGenre == .scifi || someGenre == .science || someGenre == .medical
