2D or not 2E

FYI (and that is no typo below, the compiler complains "no 5E-H" on a 
reference to 5d-h!!! and the subject above comes from the original code 
in which I named a point structure 2d--got to 5D while experimenting 
with variations):

(defstruct 5d
   (h 0 :type fixnum)
   (v 0 :type fixnum)
   )
5D
(let ((p (make-5d :h 1 :v 2)))
     (setf (5d-h p) 3))
;;; An error occurred in function MACROEXPAND:
;;; Error: There is no SETF expansion method defined for (5E-H P)
;;; Entering Corman Lisp debug loop.
;;; Use :C followed by an option to exit. Type :HELP for help.
;;; Restart options:
;;; 1   Abort to top level.
:c 1

;;; Returning to top level loop.
(defstruct 5k
   (h 0 :type fixnum)
   (v 0 :type fixnum)
   )
5K
(let ((p (make-5k :h 1 :v 2)))
     (setf (5k-h p) 3))
