Hi,

What should be the output of this code:

(define (print x . rest)
  (apply display x rest)
  (newline))

(define-syntax foo
  (syntax-rules ()
    ((_ body ...)
     (begin
       (syntax-parameterize
        ((it (syntax-rules ()
               ((_) "hello world"))))
        (print it)
        body ...)))))

(let ((it 10))
  (foo (print it)))

I only tested in two implementations Chibi and Guile.
Guile give an error but Chibi first print 10.

My implementation prints 10 10.
