Doggone.

I didn't know you had such a severe lisp.

Three Admissions.

Admission the first: while I can recognize a Lispy language from 30 yards, I know neither Scheme nor Lisp.

Admission the second: I had a pretty good idea what the result of this source code would be anyway by virtue of previous Livejournaling with relation to

jes5199.

Admission the third:

see filename.

wow! I have no idea how that works! but it's pretty. I'll likely dissect it in the morning, like I do with all pretty things.

I have mzscheme, by the way, since I had the notion that I would want to play with arc

Preliminary Autopsy.

I don't know if this helps or hinders, but upon my own dissection in DrScheme, this source code (with the same results, and an entertaining-if-pointlessly different path) was produced.

(define blinc (lambda (n) (/ n 15)))

(define jes
  (lambda ls
    (letrec 
        (
         (semsum 
          (lambda (ls)
            (if (null? ls) 1 (* (car ls) (semsum (cdr ls)))))
          )
         )
      (* (car ls) 
         (semsum 
          (cdr ls)
          )
         )
      )
    )
  )

(blinc (jes 5 1 9 9))
