=over =item $MATCH =item $& The string matched by the last successful pattern match (not counting any matches hidden within a BLOCK or eval() enclosed by the current BLOCK). (Mnemonic: like & in some editors.) This variable is read-only. The use of this variable anywhere in a program imposes a considerable performance penalty on all regular expression matches. See the Devel::SawAmpersand module from CPAN for more information. =back
