Dear monks, once again I humbly seek your wisdom,
I'm using Parallel::Forkmanager to download a list of urls, then I have other functions which process them. I would like when I download by: $url_list{$pagename} = get($url_list{$pagename}) to keep that value for $pagename, but it seems that the value instantiated within the ForkManager loop is not carried outside the loop.
I cannot simply call some sub from inside the loop and process them on the fly since I need to download all the urls before I begin processing, and I dont want to write to a file since that takes too long. This demonstrates the problem: 
use Parallel::ForkManager;
@values = (0, 0);
my $pm=new Parallel::ForkManager(2);
foreach $value (@values) {
    $pm->start and next;
    print"$value";
    $value = 1;
    print"$value";  
    $pm->finish;
};
$pm->wait_all_children;
foreach $value (@values) {
    print"$value";
};

[download]
It prints:
010100
when I want: 010111.
If any learned monk could help I would be most grateful,
cheers,
Ntav
Thats your answer to everything Homer: "lets go and live under the sea". Well it won't work this time!
