=over =item ${^MATCH} X<${^MATCH}> This is similar to C<$&> (C<$MATCH>) except that it does not incur the performance penalty associated with that variable. See L above. In Perl v5.18 and earlier, it is only guaranteed to return a defined value when the pattern was compiled or executed with the C

modifier. In Perl v5.20, the C

modifier does nothing, so C<${^MATCH}> does the same thing as C<$MATCH>. This variable was added in Perl v5.10.0. This variable is read-only and dynamically-scoped. =back
