Hi

If all you're doing is returning a value, you don't need to share anything

#!/usr/bin/perl --
use strict;
use warnings;
use threads stack_size => 4096;

## void context returns undef
threads->create( \&worker, 'LocalA', 5 ); 
threads->create( \&worker, 'LocalB', 5 ); 
threads->create( \&worker, 'LocalC', 5 ); 
{
## list context returns return value
   my @a = threads->create( \&worker, 'LocalAlfa', 15 ); 
   @a = threads->create( \&worker, 'LocalBravo', 15 ); 
   @a = threads->create( \&worker, 'LocalCharlie', 15 );
}

waiter();

exit( 0 );

sub worker {
# require LocalMyApp; return LocalMyApp::DoTheJob();
    my $obj = shift;
    my $sleeprand = shift;
    print join ' ', threads->tid,
        threads->self,  $obj, $sleeprand, "\n";
    
    my $rand = int(rand()*1000);
    sleep rand $sleeprand;
    return $rand;
}

sub waiter {    
    while( threads->list ) {
        for my $joinable ( threads->list( threads::joinable ) ) {
            print join "   ",
                $joinable->tid,
                $joinable,
                $joinable->join || 'undefined', ## return
                "\n";
        }
    }
}
