Has there ever been a discussion about some easy or straight-forward way of sharing a global instance across modules? For example, in a gui app, you might want to structure the program such that there's a global instance app (main.app) of the application that other modules might want to query. I was never to happy with importing main and then using main.app... I felt like I wanted to qualify it as a global, like: from main import global app

The simple way to do it, IMO, is to import a joint module, called something like cfg. I just did a little hack in a script with

cfg = imp.new_module('cfg')

but I don't know how well that works across modules. I think you'd need to poke it into sys.modules in order for it to be shared, but I haven't tested it.

What if there were no rhetorical questions?
