Hi Ludo,

thanks for the coding advice. This was what I've been asking for :-)
Just one point:

AFAIK, `cond` only processes the first expression where `test ` is true.
In this case, we need to process *all* cases where the test is true.
This means we need to nest the evaluation, which is ugly and hard to
read IMHO. Is there some more "linear" syntax?

(BTW: The manual [1] is not quite precise on `cond`, so I needed to test
it. Maybe I did it wrong.)
