Hello world,

We have Franz Lisp version 38.79, as distributed with Berkeley 4.2 UNIX.

I got sick of seeing the message 'foobar is Tail Recursive: etc'
and wrote a 'tail recursion optimiser'. It translates tail recursive
functions into simple iterative forms that don't cause NAMESTACK overflows.

Just in case anyone out there gets the wrong idea; I don't advocate iteration
over recursion but speed isn't necessarily a bad thing...

Have I reinvented the wheel?
Would anyone out there be interested in it? 

RSVP.
