/**
 * "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.

   * compatibility with that version and with any other compilers that interpret
   * the JLS similarly, there is no definition of copyOf() here, and the
   * definition in ImmutableSortedSet matches that in ImmutableSet.
   *
   * The result is that ImmutableSortedSet.copyOf() may be called on
   * non-Comparable elements. We have not discovered a better solution. In
   * retrospect, the static factory methods should have gone in a separate class
   * so that ImmutableSortedSet wouldn't "inherit" too-permissive factory
   * methods from ImmutableSet.
