Terrible misuse of Swift literal convertibles to automatically create Hiragana transliteration of string value.

もじれつ.swift

struct もじれつ: Printable {
    let description: String

    init(string: String) {
        var mutableString = NSMutableString(string: string) as CFMutableString
        if CFStringTransform(mutableString, nil, kCFStringTransformLatinHiragana, 0) == 1 {
            self.description = mutableString as NSString
        } else {
            self.description = string
        }
    }
}

extension もじれつ: StringLiteralConvertible {
    static func convertFromExtendedGraphemeClusterLiteral(value: String) -> もじれつ {
        return self(string: value)
    }

    static func convertFromStringLiteral(value: String) -> もじれつ {
        return self(string: value)
    }
}

let s: もじれつ = "hiragana" // ひらがな
