+ *   List<Object> objects = ...;
+ *   // Sort them:
+ *   Set<Object> sorted = ImmutableSortedMultiset.copyOf(objects);
+ *   // BAD CODE! The returned multiset is actually an unsorted ImmutableMultiset!}</pre>
+ *
+ * While we could put the overrides in {@link ImmutableSortedMultiset} itself, it seems clearer to
+ * separate these "do not call" methods from those intended for normal use.
