I guess the benefit of taking 'self' would be that it would make it
possible (though still a bit odd-looking) to have reusable __getattr__
implementations, like:
# mymodule.py
from auto_importer import __getattr__, __dir__
auto_import_modules = {"foo", "bar"}
# auto_importer.py
def __getattr__(self, name):
if name in self.auto_import_modules:
