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?
