Just paste some guile code into drracket and press debug to start stepping 
through the Guile code.

This guile code should work:

(define (list-index l k)
  (let loop ((n 0)
             (l l))
    (and (not (null? l))
         (if (eq? (car l) k)
             n
             (loop (+ n 1) (cdr l))))))

(list-index '(1 2 3 4 5 6 7 8 9) 2)

Just make sure you put the following at the top of the file:

#lang racket

Of course not all guile code would work because it's Guile and Racket
but some subsets of Guile can be used from the drracket debugger.
