I'm wondering what the simplest way is to have a set of forked processes all have access to a data element, preferably a data element which has lexical not package scope.

As you can see below, even with package scope, there is no data in @out, even though it is a package variable: 


#!/usr/bin/perl -w

use strict; use warnings;

use Parallel::ForkManager;
use LWP::Simple;
my $pm=new Parallel::ForkManager(10);

my @in = 1..5 ;
our @out;

for my $link (@in) {
  $pm->start and next;

  sleep rand 50 ;

  die if $link == 2 ;

  push @out, $link ;

  $pm->finish;

};

$pm->wait_all_children;

warn "@out"
