    Actually, the idea goes back to (at least) a XVII-th century monk
called Marin Mersenne, perhaps even much earlier. This guy studied
(among other things) what we'd call today automatic translation, and
cryptography. I strongly suspect he never heard about Bayes, Paul
Graham, or Eric Raymond. :-) Apparently, the converse is also true.
