 * <li>If a primitive type is assigned to a non-primitive type, it will attempt to box the source type and then
 * query the chained assigner for assigning the boxed type to the target type.</li>
 * <li>If a non-primitive type is assigned to a primitive type, it will unbox the source type and then attempt a

 * type.</li>
