I really took an instant dislike to the original demo code. Matthias' "why
not" version is much more to my taste.

The "why not" version seems more like C++. The "demo" version seems like
something left over from the C days.

My own interest in a Boost GUI library would be for pretty simple
applications and for teaching C++. Maybe a few medium complexity apps if
the GUI requirements weren't too hard to meet.

Now if such a GUI could also handle more complex apps, fine, but only if
there is no impact on the simple "hello, world" level applications.

Even the "why not" version seems overly complex compared to a console
iostreams "Hello, world". Why not just:

      winout << title("Example window") << button("Hello, world!")
             << wait_for(delete_signal);

I'm not necessarily pushing that exact approach, but just pointing out more
C++-like alternatives.
