well, FWIW, here's how I would do it in Common Lisp:

    (defun make-3-point-transformation (point-1 point-2 point-3
					point-1-image point-2-image)
      (multiple-value-call #'make-3-point-transformation*
	(point-position point-1)
	(point-position point-2)
	(point-position point-3)
	(point-position point-1-image)
	(point-position point-2-image)))
