Is it a common expression? Was the word "contract" alone in use in
program design or programming before DbC was coined? For me the single
word was totally new for any meaning in computer programming at
something 1990. The phrase "design by contract" may have occasionally
appeared in sales of construction or even program design services, but
not as a technical term.
