Yeah, I am. But there's this annoying difficulty with accessing variables. I have to send messages around the world and get responses back, I can't just type "global foo" and have foo be the same thing here and everywhere else. I mean, it's called "global" for a reason, why can't it be the same "foo" for every single process in the world? Or if it's okay for "globals" to not be globally shared, then why is it a problem for them to be per-module? ChrisA
