This is new to me but it seems like a good idea - if the extra 'get' is
not too much of a hit - and it is explained well in the docs.

However, there seems to be a bug in the code somewhere - try running
'perl t/043_Gtk_Window.t' and see what I mean. The resizable($TRUE)
call does not set the value correctly although the resizable() call 
gets the correct value. BTW set_resizable($TRUE) works fine.

I agree with this - I am always attaching hash keys/values to objects
that I have constructed.

This brings up another question - why is a widget held as a blessed do{}
rather than a hash as was done in Gtk-Perl? Data::Dumper outputs a
widget as  
    bless( do{\(my $o = 137539536)}, 'Gtk2::Button' )

and I cannot add hash keys/values to this as I used to do when the
widget refs were held as
    bless( { '_gtk' => 137252624 }, 'Gtk::Button' );
