I think the problem is with these functions

Where I use (mcode '(macro-adder (* 3 5) (* 5 7)))

macro-adder being a macro defined with defmacro

(defun mobject (object &optional bfname)
  (or bfname (setq bfname buffer-name))
  (estring (pp-to-string object) bfname))

(defun mcode (code &optional bfname)
  (or bfname (setq bfname buffer-name))
  (apply 'mobject '((macroexpand code) bfname)) )
