(defmacro dfexpr (name arglist &body body)
  (let ((%name (gensym (string name))))
    `(prog1
       (defmacro ,name ,arglist
         (list ',%name 
          ,@(mapcar #'(lambda (arg) `(list 'quote ,arg)) arglist)))
       (defun ,%name ,arglist ,@body))))

Note that this won't work if the arglist contains keywords (eg. &rest).
 
In XCL you'd probably want to use:

(defdefiner dfexpr il:functions (name arglist &body body) (let ...))
