如何实现
自带许多的
typealias ALC = ExpressibleByArrayLiteral
typealias BLC = ExpressibleByBooleanLiteral
typealias DLC = ExpressibleByDictionaryLiteral
typealias FLC = ExpressibleByFloatLiteral
typealias NLC = ExpressibleByNilLiteral
typealias ILC = ExpressibleByIntegerLiteral
typealias SLC = ExpressibleByStringLiteral
class Person: ExpressibleByStringLiteral {
let name: String
init(name value: String) {
self.name = value
}

    required convenience init(stringLiteral value: String) {
        self.init(name: value)
    }

    required convenience init(extendedGraphemeClusterLiteral value: String) {
       self.init(name: value)
    }

   required convenience init(unicodeScalarLiteral value: String) {
         self.init(name: value)
    }
}
