12 | =head2 The C<$*> variable has been removed |
| 13 | ||
| 14 | C<$*>, which was deprecated in favor of the C</s> and C</m> regexp | |
| 15 | modifiers, has been removed. | |

19 | =head2 Tied Arrays with Negative Array Indices |
| 20 | ||
| 21 | Formerly, the indices passed to C<FETCH>, C<STORE>, C<EXISTS>, and | |
| 22 | C<DELETE> methods in tied array class were always non-negative. If | |
| 23 | the actual argument was negative, Perl would call FETCHSIZE implicitly | |
| 24 | and add the result to the index before passing the result to the tied | |
| 25 | array method. This behavior is now optional. If the tied array class | |
| 26 | contains a package variable named C<$NEGATIVE_INDICES> which is set to | |
| 27 | a true value, negative values will be passed to C<FETCH>, C<STORE>, | |
| 28 | C<EXISTS>, and C<DELETE> unchanged. | |
