 * are guaranteed to execute before any "before" callbacks implemented by
 * {@code Extension2}. Similarly, given the two same two extensions registered
 * in the same order, any "after" callbacks implemented by {@code Extension1}
 * are guaranteed to execute after any "after" callbacks implemented by
 * {@code Extension2}. {@code Extension1} is therefore said to <em>wrap</em>
