Little app using gtkD, how to make it well?

[Romain via Digitalmars-d-learn]

Hello,

I started an application using gtkD and libusb-d. I would love to 
get some hints about how to make good use of D since I'm a java 
developper and maybe use too much of it in D code or doing wrong 
things.

The program will only work with msi laptop that have a 
steelseries keyboard, but it may work with other hardware and is 
untested.

I think the program leak (or don't release the usb handle) when 
exiting using ctrl+c for example, so I may move the Keyboard and 
all libusb object in the global scope and use them by using a 
kind of sigterm handler. Initially I used the "scope(exit){}" but 
it don't work :)


Thanks you
