      Defining two variables, where the second depends on the first::

        tal:define="mytitle template/title; tlen python:len(mytitle)"

         ignore t by tlen

         how do you access the defined vars from a python call?
         i.e. <span tal:replace="python:method(mytitle)"> value </span>
