The opposite of "patently false" is "patently true". Do the other people
have the proof that C _is_ cheaper? No doubt they will mumble about
"we don't need proof, we all _know_ that it is cheaper". (You may get
the same argument from Ada people). However arguing from
a position of _assuming_ the C claims are true will always put you behind.
