And taking it even farther, all of the blackbox aspects of import go away. For instance, the implicit, hidden importers for built-in modules, frozen modules, extensions, and source could actually be set on sys.path_hooks. The Meta path importer that handles sys.path could actually exist on sys.meta_path.
