That's not quite true. C++ has had bool as a builtin type, and false
and true as keywords, since its first ISO standard, in 1998. But the
first and second editions of Stroustrup's "The C Programming Language"
(1986 and 1991, respectively) don't mention bool, and for example
document that the "!" operator yields a result of type int with the
value 0 or 1.
