That was obvious and not what I really asked, but thanks anyway :)
Well, then I'm afraid that I don't get what you were asking, because
that's what

By "reaching that state" I meant a state as would be visible by code other
than the object constructor or destructor. As Michel said, Andrei's
proposal leaves the object in a state where its invariants could fail.
