/**
 * "Overrides" the {@link ImmutableMultiset} static methods that lack {@link
 * ImmutableSortedMultiset} equivalents with deprecated, exception-throwing versions. This prevents
 * accidents like the following:
 *
 * <pre>{@code
 * List<Object> objects = ...;
 * // Sort them:
 * Set<Object> sorted = ImmutableSortedMultiset.copyOf(objects);
 * // BAD CODE! The returned multiset is actually an unsorted ImmutableMultiset!
 * }</pre>
 *
 * <p>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.
