         use Tie::RefHash;
         tie %h, 'Tie::RefHash';
         $a = [];
         $b = {};
         $c = \*main;
         $d = \"gunk";
         $e = sub { 'foo' };
         %h = ($a => 1, $b => 2, $c => 3, $d => 4, $e => 5);
         $a->[0] = 'foo';
         $b->{foo} = 'bar';
         for (keys %h) {
            print ref($_), "\n";
