Let me just briefly summarize why I think reinitialize-instance should
be an option:

Let's say I have a window, and I want a quit button (and some other
buttons). What I want to do is then

(let ((window (make-instance 'window)))
  (apply #'reinitialize-instance window 
         :child (make-instance 'button 
                  :signal (list 'clicked #'widget-destroy :object window))))

But at present I can't do that, because :child processing is only in
initialize-instance of containers, not shared-initialize.

I hope that my intent (and why I can't achieve it currently -- I'd
have to use box-pack explicitly everywhere) is relatively clear. As I
say, more details (I hope) to follow when I finish this translation
exercise.

Cheers,

Christophe
