break Break out of a given() block. This keyword is enabled by the "switch" feature; see feature for more information on "switch" . You can also access it by prefixing it with CORE:: . Alternatively, include a use v5.10 or later to the current scope.

length EXPR length Returns the length in characters of the value of EXPR. If EXPR is omitted, returns the length of $_ . If EXPR is undefined, returns undef. This function cannot be used on an entire array or hash to find out how many elements these have. For that, use scalar @array and scalar keys %hash , respectively. Like all Perl character operations, length() normally deals in logical characters, not physical bytes. For how many bytes a string encoded as UTF-8 would take up, use length(Enc

$<digits> ($1, $2, ...) Contains the subpattern from the corresponding set of capturing parentheses from the last successful pattern match, not counting patterns matched in nested blocks that have been exited already. These variables are read-only and dynamically-scoped. Mnemonic: like \digits.
