 Hi Danny, Matthew,
Thanks for your comments. I did some more reading in sections 12.3 and 
of the mzscheme manual. I found that in a module #'a is expanded to
 (#%top . a) if a is not bound in the module and to plain a if it is. 
is correct, of course, and it explains the difference between the two
pieces of code. Best wishes, Jos

((((lambda(x)((((((x x)x)x)x)x)x))
   (lambda(x)(lambda(y)(x(x y)))))
  (lambda(x)(write x)x))
 "greetings, Jos")
