This is similar to $& ($MATCH) except that it does not incur the performance penalty associated with that variable.

See "Performance issues" 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 /p modifier. In Perl v5.20, the /p modifier does nothing, so ${^MATCH} does the same thing as $MATCH.

This variable was added in Perl v5.10.0.

This variable is read-only and dynamically-scoped.
