OK, I think I'm getting the idea. You're saying that the "other" file
doesn't need to know all the definitions of the classes in the first
file, it just needs to know that they are classes, so we put "dummy"
class definitions in global.rb, and that's all anyone else needs to
know. Yes?

I assume that's your idea. In either case, thanks for the idea!

I'm giving the best advice I have. You get to decide whether it's true for you.
