qobject_cast breaks; the meta object system reports and uses the wrong
class name (so things like "inherits", "className" etc. don't work);
tr() uses the wrong context; and so on.
qobject_cast breakage may be serious enough to justify an automatic -1
to all public QObjects-without-Q_OBJECT classes.
