Voici quelques exemples de listes de paramètres (de McCLIM) :
(defun make-rotation-transformation (angle &optional origin)
(if origin
(make-rotation-transformation*
angle (point-x origin) (point-y origin))
(make-rotation-transformation* angle 0 0)))
(defun find-frame-manager (&rest options
&key port &allow-other-keys)
(declare (special *frame-manager*))
(if (boundp '*frame-manager*)
*frame-manager*
(if (and *default-frame-manager*
(frame-manager-p *default-frame-manager*))
*default-frame-manager*
(first (frame-managers
(or port (apply #'find-port options)))))))
(defun make-pane (type &rest args)
(apply #'make-pane-1 *pane-realizer*
*application-frame* type args))
