RECUR
A simple library for Scheme's named LET.
RECUR is a simple Lisp alternative Scheme's "named-LET". Scheme allows
one to iterate like the following:
(define (factorial n)
(let fact ((n n)
(prod 1))
(if (zero? n)
prod
(fact (- n 1)
(* n prod)))))
This is a useful idiom for Lisp as well. With this library, it is written
(defun factorial (n)
(recur fact ((n n)
(prod 1))
(if (zerop n)
prod
(fact (1- n)
(* n prod)))))
This library exports a single macro, RECUR:RECUR, which is a
replacement for Scheme's named-LET. The only caveat is that tail
recursion is not strictly supported, though many implementations do
support it (with some combination of OPTIMIZE declarations).
