Good to mention is also this code to show the pretty print formatted
lisp object representation of the current Org buffer:

#+BEGIN_SRC emacs-lisp
  (let ((out (org-element-parse-buffer)))
    (setq eval-expression-print-length nil)
    (setq eval-expression-print-level  nil)
    (switch-to-buffer (get-buffer-create "*prettyprint*"))
    (erase-buffer)
    (insert (pp-to-string out))
    (goto-char (point-min))
    (emacs-lisp-mode)
    (setq truncate-lines t))
#+END_SRC

Not sure if the following should be supported by
org-element-interpret-data:

#+BEGIN_SRC org
  ,variable declaration in some programming languages:
  ,- Perl :: the variable declaration can be implicit
  ,- C ::
  ,  #+BEGIN_SRC C
  ,    time_t variable_name;
  ,  #+END_SRC
#+END_SRC

The above command for Bijectivep of (org-element-interpret-data
(org-element-parse-buffer)) shows BEGIN_SRC on the same line as
"- C ::" but I expect it on a separate line like in the original. The above
command for prettyprint of (org-element-parse-buffer) alone looks ok
to me.
