The solution you wrote about in another thread allowing both ways of 
returning a value might be the best. Great (and very perlish) idea!

Why do you do that? Just leave the argument where it is and noone will 
complain. Users that don't read Gtk2::api in the first place will not 
even know that it is special if they do not need the return value 
mechanism. It just works as in the C-docs.
