Thanks. As far as I can see, both programs just create a plain list of
routine names. The lists do not show dependences of a routine on the
other ones, or any other cross-reference information.

I've started to write a little cross-reference program myself. ATM, if
I use it to parse e.g. "search.ex", the output is:

   type boolean()
      -- called by <main>, final_stats(), scan(), look_at()

   function alphabetic()
      -- called by final_stats(), <main>

   function fast_lower()
      -- called by scan(), <main>

   ...

That's what I mean.

That sounds very nice. When I first read about your "big plan", I
thought: "Hm, does that mean anything to me as the Euphoria programmer?".
Now I see that the new structure of Euphoria provides the basis for a
bunch of improvements. Great!
