Hi all,

I am trying to write my first language based upon Beautiful Racket (which 
is amazing, BTW!).

Almost everything works, but when I expand a syntax fragment, I need to add 
a print function to make the result display (display, displayln, writeln, 
etc.).
I followed the "funstacker" tutorial ( source listing here ) and the 
tutorial does use "display" in the "funstacker-module-begin" macro. 
<https://beautifulracket.com/funstacker/source-listing.html>

However, I expected something like:

(define-syntax my-module-begin
  (make-wrapping-module-begin #'handle-sentence))

(define-syntax (handle-sentence stx)
  (syntax-case stx ()
    [(handle-sentence _) #'(#%datum . 2)]))

in my expander to allow me to return 2, but in fact it only displays 2 
(apparently as a string) if I do:

(define-syntax (handle-sentence stx)
  (syntax-case stx ()
    [(handle-sentence _) #'(display (#%datum . 2))]))

How can I return 2 as a number, as you get when typing 2 in the #lang 
racket REPL?

Thanks!
Raoul
