 * by a sequence of {@link BeanPropertyWriter}s that will handle
 * access value to serialize and call appropriate serializers to
 * write out JSON.
 *
    
 * Implementation note: we will post-process resulting serializer,
 * to figure out actual serializers for final types. This must be
 * done from {@link #resolve} method, and NOT from constructor;
 * otherwise we could end up with an infinite loop.
