Details:

(define-syntax ignore-variables
  (syntax-rules ()
    ((IGNORE-VARIABLES x ...)
     (DECLARE (IGNORE x ...)))))

(let ((x 5))
  (ignore-variables x)
  0)
;Ill-formed special form: (#[syntactic-closure 12] (#[syntactic-closure 13]
x))

;;; Should be

;Value: 0

;;; The problem is that in the output of IGNORE-VARIABLES, `IGNORE'
;;; occurs not as a symbol but as an alias, which confuses the part
;;; of the syntaxer that processes declarations.
