I don't see how you can say that "primitive low level" languages misuse 1
and 0 as true and false in boolean manipulations. After all, these same
"primitive" languages provide the programming for virtually every electronic
consumer product including cell phones, automobiles, tv's, ... It may not be
pretty, but it sure works, which would not seem to me to be a misuse.
