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) {
