   Sorry Matthias for being flippant, but in my mind, that's tantamount
   to saying that a Turing machine would take you far.

It's not. Read "On the expressive power of programming languages."

   I actually have at least one application (PGG) which is really dependent
   upon CALL/CC, but beside that, I often just plain *want* to use CALL/CC
   even when I could, in principle, with some more thought, use something
   else.

   Anyway, this discussion really belongs some other place.

Yes, but where else do serious people discuss such a question?
