This copy constructor
A(const A& a) { b_ = !a.b_; }
can be called humorous at best.
Since the compiler is entitled to optimize away its invokation in
certain situations, there's now way to predict whether you deal with
an original or a copy of it (with the value of b_ negated) [leaving
open the question whether the terms "original" and "copy" should be
used here].
