What do you suggest ? Use lisp only for toy projects and blame other
language for failures?

Are you referring to Halting problem ?

0-th Fibonacci is 0, IIRC. Furthermore, the use of loop's repeat clause is
appropriate here. Thus,

(defun fib (n)
(loop repeat n
for a = 0 then b
and b = 1 then (+ a b)
finally (return a)))

I suggest no further discussion of Lisp's image problem now that it is
the fastest growing language on Earth and will soon push all the others
into the sea.

I suggest we shut down c.l.l and everyone get to work writing computer
applications. Remember those? The reason we program? Hello? Anybody?
