the extra ->window is still correct.

you have hooked your signal to the "destroy" event --- this gets called 
as the widget is being destroyed, specifically, i think, *after* then 
window is off the screen.  that means the GdkWindow doesn't exist anymore.

what you actually want, methinks, is the "delete-event", which is 
exactly when the user clicks the "x" in the window manager.

   $window->signal_connect("delete-event", sub { buhbye($window); });

when i did that, i got

   GtkWindow
   x: 53, y: 730

as the output.


/me slaps forehead for not having seen it earlier


in a larger application, you'll want to be able to save the window 
position from more than just a window-manager kill, so this code should 
actually go into your app's "quit" handler, and have the delete-event 
signal call the same thing that "File->Quit" (or its equivalent in your 
app) calls.
