I didn't, only the message that started this thread.  It left me confused.

Would it suffice to define a new expression type, so you'd have something like

  <something tal:define="result yanged:/foo/bar">
    ...
  </something>

That's something the TALES engine is designed to support.  For Zope 3,
new expression type handlers can be registered with the component
architecture; I don't remember how it's done in Zope 2.
