Thanks for your insight.

So I went back to twig technology and copied the hash via 
sub copy_hash {
    my $hr = shift // return {}; # get hash to copy or return empty ha
+shref if not given

    my %copy = ();

    while (my ($k, $v) = each %{$hr}) {
        $copy{$k} = $v;
    }

    return \%copy;
}

Which works. So this is it? Best way to go?
