Logical or and Exclusive Or Binary "or" returns the logical disjunction of the two surrounding expressions. It's equivalent to || except for the very low precedence. This makes it useful for control flow: print FH $data or die "Can't write to FH: $!"; This means that it short-circuits: the right expression is evaluated only if the left expression is false. Due to its precedence, you must be careful to avoid using it as replacement for the || operator. It usually works out better for flow con

${^PREMATCH} This is similar to $` ($PREMATCH) 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 ${^PREMATCH} does the same thing as $PREMATCH . This variable was added in Perl v5.10.0. This variable is read-only and dynamically-scoped.
