     * <li>If <code>type</code> is a <code>Class</code>, it is returned as-is.</li>
     * <li>If <code>type</code> is a parameterized type, its raw type is returned.</li>
     * <li>If <code>type</code> is a wildcard type, its (first) upper bound is returned.</li>
     * <li>If <code>type</code> is an array, the raw class of its elements is returned.</li>
     * <li>Otherwise, <code>null</code> is returned.</li>

 *   <li>Next, if only one {@code Bar} is null, that null value is treated as <i>lesser</i>
 *   <li>Finally, natural ordering is used (i.e. the result of {@code Bar.compareTo(Bar)} is
 *       returned)
 * </ol>

 * <p>Alas, {@link #reverse} is a little different. As you read backwards through a chain and
 * encounter a call to {@code reverse}, continue working backwards until a result is determined, and
 * then reverse that result.
