=head1 Core Enhancements
+=head2 Tied Arrays with Negative Array Indices
+
+Formerly, the indices passed to C<FETCH>, C<STORE>, C<EXISTS>, and
+C<DELETE> methods in tied array class were always non-negative. If
+the actual argument was negative, Perl would call FETCHSIZE implicitly
+and add the result to the index before passing the result to the tied
+array method. This behavior is now optional. If the tied array class
+contains a package variable named C<$NEGATIVE_INDICES> which is set to
+a true value, negative values will be passed to C<FETCH>, C<STORE>,
+C<EXISTS>, and C<DELETE> unchanged.
