(for the list's benefit: Eric and I have had a few out-of-the-list
exchanges but as everything now seems to be working fine, I thought I'd
reconnect the thread to the list...)

Eric, 

just to confirm that it all seems to work just fine from a cold boot of
emacs without any extra (require 'ob-eval).  My babel configuration has
the following:

#+begin_src emacs_lisp
(org-babel-do-load-languages
 'org-babel-load-languages
 '((R . t)
   (calc . t)
   (ditaa . t)
   ...
#+end_src

and that's about it really.  Evaluating the calc examples you sent
initially all work perfectly.

Using src_calc{5-2}, for instance, also works just fine for export.

I now wonder if it would be worthwhile discussing the choices you have
made regarding stack versus algebraic evaluation.  I would rather have
the quote mean an algebraic expression, just from the simple reason that
these will be longer than stack operations and so the overhead of a
quote is smaller as a percentage of keystrokes...

Anyway, thanks for this.  I think this is going to be quite useful but
it does mean really getting down and learning emacs calc...
