Hello,
I am trying to write a (simple) function to convert s-expressions to XML.

(define atom?
(lambda (x)
(and (not (pair? x)) (not (null? x)

Hello,
I am trying to understand the defstruct macro from the "teach yourself
scheme in fixnum days" tutorial, which can be found in chapter 9 at

easier to go through the examples, I've come up with the following macro:
;;; Helper to visualize

Hello,
I would like to try some GUI stuff with guile. Since I have some experience
with Tk (with perl and ruby), I tried Tk following
http://www.galassi.org/mark/mydocs/guile-programmer_2.html:
(require 'Gwish)
(use-library tcl)
(use-interface tcl)
(use-interface tclhack)
(tk-main-loop)

Hello,
I am about to learn scheme by working through some tutorials. My first

Now I would like to use structures as described in
