Perl6::Builtins(3)    User Contributed Perl Documentation   Perl6::Builtins(3)

NAME
       Perl6::Builtins - Provide Perl 5	versions of the	new Perl 6 builtins

VERSION
       This document describes Perl6::Builtins version 0.0.3

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};

DESCRIPTION
       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.

INTERFACE
       "system"
	   If "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 $!.

       "caller"
	   If "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)[3];

	   you can write the much more readable:

	       $subname	= caller->{sub};

DIAGNOSTICS
       None.

CONFIGURATION AND ENVIRONMENT
       Perl6::Builtins requires	no configuration files or environment
       variables.

DEPENDENCIES
       This module uses	the Contextual::Return module.

INCOMPATIBILITIES
       None reported.

BUGS AND LIMITATIONS
       No bugs have been reported.
