I think the whole API would be nicer and more obvious if return values
were, well, returned.

Is the 'RetVal' way of doing things a constraint forced by the
underlying Gtk+ system in some way?

The whole notion of having to set a return value when the return type of
the delegate is actually 'void' seems likely to really confuse newcomers
to Gtk#...
