Have you found some way of deal with class signals (or whatever you want
to call the signal slots that are held in the class object) in a
reasonable manner? Then again, C++ isn't an interpreter, so you won't have
many of the difficulties I ran into with Perl.

Don't forget, in C++ your constructor can call the ancestors constructor.
That doesn't work under gtk+, currently. Which we may want to take as a
hint.:-)
