Oh yes, one might want to display the shared data. This will do.

$SIG{'TERM'} = sub {
    if (MCE->wid > 0) {
        # worker
        MCE->exit(0);
    } else {
        # parent
        say 'Parent is ready to dump';
        say 'Dumping: ' . Dumper \%hash;
        MCE::Signal::stop_and_exit('TERM');
    }
};
