This LGTM.

The same snippet is commented out in rtx-eval-with-estate:

;		; Don't eval operands for syntax expressions.
;		(if (eq? (rtx-style rtx-obj) 'SYNTAX)
;		    (apply fn (cons estate (cdr expr)))
;		    (let ((operands
;			   (/rtx-eval-operands rtx-obj expr estate)))
;		      (apply fn (cons estate operands))))

And it is (apply fn (cons estate (cdr expr))) there.
