Why does the following function give

Lisp error: (wrong-type-argument stringp bfname)

What can I do to fix this problem for the buffer name ?

(defconst buffer-name "BFTEMP")

(defun estring (string &optional bfname)
  "Show STRING in a temporary buffer."

  (or bfname (setq bfname buffer-name))

  (with-output-to-temp-buffer bfname
    (princ string)
    (emacs-lisp-mode)))

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)) )

                    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Yes, as in not a string (the `stringp' error).
