 Maybe it is a question of formating but SerialX will be the shortest one anyway. Because instead of having some sort of key to the value you simply have its order (index)!
 And value's data type is specified by suffix if it is a primitive data type or simply by package name as the first argument in case of an object! Other arguments are then specified by an SerializationProtocol!
