I can export another namespace that doesn't include whatever I imported. So import doesn't have to be `transitive,' as I said. Your analogy with NFS doesn't make sense, because in Unix-land (where I assume you're talking about), you have a single, global namespace.

I get to join the rest of the masses in ignoring his inanities! - Dan C. (Actually, I'm filtering him into another folder, so that I have something to laugh at every now and again when I'm feeling bored.)
