Yes, but I was thinking of exporting the result to something nice, so I
wanted to tell org I was in calc mode. In fact, I'm not sure to like how
calc deals with delimiters: it's not liking the "#+..." if there is no
blank line. I know it's configurable, though.

Yes, I basically read through the info page. The useful shortcuts I
picked were:

- C-x * u: update the formula (it's almost C-x * e C-x * e, except it
  will still work if another formula is currently in embedded mode)
- C-x * d: duplicate the formula and enter embedded calc mode
- s = in calc mode: add the nice => thingy

Well, it does not work as such. I don't know how to define mutually
recursive functions in calc, and that was basically my question. (But
then one may then use a real programming language at that point.) The
manual never really defines functions, and it seems that what I want to
do is rewrite things, but I cannot find a way to do it correctly.
