in reply to Name spaces and Perl::Tk coding style
You are correct, put it into modules if you can. When I wrote an app with Win32::GUI I found myself constantly frustrated with scrolling through so much of the init code. Pages and pages just to setup the windows and labels. When I put it into modules it was easier to work with, but then I went overboard. I started trying to make it too much of a general purpose module for GUI apps, it got too complex, and got pushed back to the end of my "to work on later" list, and I haven't thought about it in years.
Ah, so much wasted code, never to see the light of day...
