syntax-rules problem

[David Pirotte <david@altosw.be>]

Hello,

	guile version:	2.0.0.160-39be

this used to work:

(define-syntax push*
  (syntax-rules ()
    ((push* . ?args)
     (set! (car (last-pair ?args))
	   (cons* ?args)))
    ))

scheme@(guile-user)> (define ll '(1 2 3 4 5))
scheme@(guile-user)> (push* 'a 'b ll)
ERROR: In procedure setter:
ERROR: In procedure setter: Wrong type argument in position 1: #<procedure car (_)>

Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.
scheme@(guile-user) [1]> ,bt

In current input:
      3:0  1 (#<procedure a164730 at <current input>:3:0 ()>)
In unknown file:
           0 (setter #<procedure car (_)>)
scheme@(guile-user) [1]> 


Cheers,
David
