Hi,
I found a difference in running a file with "mzscheme -f <file>" and with
"plt-r6rs <file>" involving syntax-case. For the first you should comment the
import. Then the first will error:
cdr: expects argument of type <pair>; given #<syntax:blah>
and the second will produce the expected output:
(a b (+ c -1) d e)
The code is:
(import (rnrs)) ;comment this line for mzscheme
(define make-next-coords
(lambda (x)
(with-syntax (((name ... pos inc) x))
(let ((pos (syntax->datum #'pos)))
(let f ((names #'(name ...))(pos pos))
(with-syntax (((name rest ...) names))
(if (zero? pos)
#'((+ name inc) rest ...)
#`(name #,@(f (cdr names)(- pos 1))))))))))
(write (syntax->datum (make-next-coords #'(a b c d e 2 -1))))
Is this a bug or is there another explanation?
Thanks,
Marijn
