    Another way to look up the variable *sequence-item* in a DTML
    expression is to use the *getitem* utility function to explicitly
    look up a variable::

      The square of <dtml-var sequence-item> is:
      <dtml-var expr="_.getitem('sequence-item') * 
                      _.getitem('sequence-item')">
