// PLEASE DON'T USE THIS HEADER FILE. If you are using a class
// type, A, which provides operator== but not operator!= you
// can do
// #include <utility>
// using std::operator!=;
//
// before you do
// if (x != y) { ...
//
// but if one reflects on it dispassionately, it should be clear
// that this solution is much more verbose than the obvious one,
// which is to just write
// if (!(x == y)) { ...
//
// instead. If you find you need operator!= a lot, it is better
// to provide an operator!= near the declaration of class A, to
// save the user the trouble of #including <utility> and typing
// a `using' statement.
