You can also work directly with tuples, and reference the elements in
an arbitrary order, as the example below illustrates.  The prefix on
the dtml-in tag is not necessary, but I think it reads better:

<table>
  <dtml-in "[ ('John', 'Hunter', 1234, 'jdhunter at paradise.lost'),
              ('John', 'Doe', 1235, 'billyboy at yahoo.edu'),
              ('Jane', 'Smith', 1238, 'jane at myserver.com')]" 
           prefix="people">
    <tr>
      <td><dtml-var "people_item[0]"> <dtml-var "people_item[1]"></td>
      <td><dtml-var "people_item[3]"></td> 
      <td><dtml-var "people_item[2]"></td>
    </tr>
  </dtml-in>
</table>
