/**
 * "Overrides" the {@link ImmutableSet} static methods that lack
 * {@link ImmutableSortedSet} equivalents with deprecated, exception-throwing
 * versions. This prevents accidents like the following: 
   {@code
 *
 *   List objects = ...;
 *   // Sort them:
 *   Set sorted = ImmutableSortedSet.copyOf(objects);
 *   // BAD CODE! The returned set is actually an unsorted ImmutableSet!}
 *
 * 
While we could put the overrides in {@link ImmutableSortedSet} itself, it
 * seems clearer to separate these "do not call" methods from those intended for
 * normal use.

   * The result is that ImmutableSortedSet.copyOf() may be called on
   * non-Comparable elements. We have not discovered a better solution. In

   * so that ImmutableSortedSet wouldn't "inherit" too-permissive factory
   * methods from ImmutableSet.
