[htmltmpl] loop through a hash structure without knowing the hash keys?

[Boon C. <was...@ya...>]

  I can't find a way in the doc to loop through hash without knowing the  keys in the hash.  If this feature is not available, I think the  fact that the template has to always such intimiate knowledge of what's  being passed to it is not always a good thing, it also makes it  impossible to just dump out all the data on the HTML end with a simple  statement.
  
  e.g.
  <tmpl_loop students>
  <tmpl_var name>
  </tmpl_loop>
