Callback Argument Marshalling

Gtk Developers:

I've been working on providing a Gtk interface to an interpreted
language and am curious about the argument marshalling feature of the
GTK API.
        
I had previously made C callbacks for every unique signal, and did the
marshalling myself.  But since I stumbled across the argument
marshalling feature, I've been tempted to use it instead.  How
robust/complete is this feature?  Do all signals support it?  How does
it work with the low-level (GdkEvent) signals?
        
Thanks for the help.
