Hi!
I use the latest cvs emacs. When I define a function like this:

(defun test-o (&optional arg)
  (interactive "P")
  (message "arg: %S" arg))


M-x test-o yields:
Debugger entered--Lisp error: (void-function &optional)
  (&optional arg)
* call-interactively(test-o)
  execute-extended-command(nil)
  call-interactively(execute-extended-command)

There seems to be something wrong with the lisp parser...

Stefan.
