Well, it is not a real-life use. I do not have to solve this problem in any
of my projects. I had a hypothesis that "using veneers is safe", i.e. If I
derive from a type that does not have virtual functions but I do not add
any changes to the layout, it is a safe thing to do. It turns out that
5.3.5/3 makes it unsafe, but for no good reason.

Well, having rules simpler has merit, but it also prevents certain styles
of programming.
