   * Record classes can implement {@code Serializable} and receive treatment defined

   * <cite>Java Object Serialization Specification,</cite> Section 1.13,
   * "Serialization of Records"</a>. Any declarations of the special
!  * handling methods discussed above are ignored for record types.<p>
   *
   * The serialization runtime associates with each serializable class a version
   * number, called a serialVersionUID, which is used during deserialization to
   * verify that the sender and receiver of a serialized object have loaded
   * classes for that object that are compatible with respect to serialization.
