I'm not sure I understand this; could you point to the relevant part of the PEP and what you would be adding? Thanks.

The PEP does not explicitly state how to signal that a loader cannot load a module it is asked to. This could happen if someone called a loader without consulting its respective importer. I would want to add something like: """ If the loader is unable to load the specified module and a specific exception is not raised in determining this, ImportError is raised. This may occur if a loader is called without first consulting an importer as to if the loader can load the specified module but the loader is aware of the fact it cannot fulfill the request made. """

(The rest of your comments sounded fine, btw.)

Great!
