Perl6::Builtins Description

Perl6::Builtins is a Perl module that provides erl 5 versions of the new Perl 6 builtins. Perl6::Builtins is a Perl module that provides erl 5 versions of the new Perl 6 builtins.SYNOPSIS use Perl6::Builtins qw( system ); system $system_cmd or die "Could not $system_cmd: $!"; my $package = caller->{package}; my $file = caller->{file}; my $line = caller->{line};Several of the builtins in Perl 6 have different (i.e. more useful, less confusing) behaviours than their Perl 5 counterparts. This module provides Perl 5 versions of those builtins.INTERFACEsystemIf system is loaded on the use line, the builtin is altered so that it returns true if the system command suceeds. In any other context, the command returns the value in $!.callerIf caller is loaded on the use line, the builtin is altered so that it behaves as in Perl 5 in scalar and list contexts. However, if the result of a call to caller is used as a hash reference it returns a reference to a hash with the following keys:'package' 'file' 'line' 'sub' 'args' 'want' 'eval' 'require' 'hints' 'bitmask'with each of the values for these keys being the equivalent item from the list returned by caller in list context. This is useful because it means that, instead of: $subname = (caller);you can write the much more readable: $subname = caller->{sub}; Requirements: · Perl
