[Luna-scheme-discuss] contrib + any work going on w luna ?

[<bri...@co...>]

Hello -- I have recently discovered Luna Scheme.  I have it building in the IDE on windows and I fixed a bug in named 'let' so that NOW

(let z ((x 3)) x) is equivalent to

(letrec ((z (lambda (x) x))) (z 3))

I would like some help with the following problem:

(let z ((x 5))
  (if (= x 0)
      1
      (* x (z (- x 1)))
  ))

results in 5 instead of the correct 120.  My initial investigations lead me to examine the tail-recursion implementation (I hypothesize that z is being improperly converted to a tail-call).

Anyone out there?  Anyone interested in helping me?
