When you write:
import A from "B.js";
that's implicity wrapping "B.js" in a module which you create (unnamed
here), and then importing `A` from it. So yes, `Foo` and `Bar` are
nested modules. It's important for the importer to control the outer
module in the import.

Yes, that would be the correct way to write this example,
