    <TMPL_LOOP>s within <TMPL_LOOP>s are fine and work as you would expect.
    If the syntax for the param() call has you stumped, here's an example of
    a param call with one nested loop:

      $template->param(LOOP => [
                                { name => 'Bobby',
                                  nicknames => [
                                                { name => 'the big bad wolf' }, 
                                                { name => 'He-Man' },
                                               ],
                                },
                               ],
                      );
