A code attack which had to guess the language would be harder (N cracking
attempts presuming N different languages, N large and finite) but definitely
not impossible. Perhaps the N-attempt requirement would put a cracking
attempt beyond practical feasibility if the code was already tough, however.
(Does this make any sense or am I just talking through my hat?)
