Ever heard of the loop macro?
Yes, the loop macro is a good example for the argument against lisp. Lisp has features to support iteration that date back to the time before it was understood that tail recursion is equivalent to iteration. In fact, even in the early '90s most common lisp compilers didn't implement tail-merging. I doubt there is any program implemented using the loop macro that couldn't be more elegantly implemented recursively. In fact, when writing in lisp or scheme, I always write recursively now that I can depend on compilers to tail- merge. -------------------------------- David F. Place mailto:d@vidplace.com
