You can always define constants, which I do for the more common special 

use constant Gtk_true => 1;
use constant Gtk_fill => Gtk_true;
use constant widget_width => 2;
use constant widget_height => 3;

but keeping track of every piddly little one is a pain.

Here's what I usually do for something like this:

my ($widget_width, $widget_height) = @{$w->allocation}[2,3];

That's pretty much painless and self-documenting.
