Sorry, I forgot push a "Publish All My Drafts" button. Please consider other my comments to first patch. I also have added new comments about length_hint().

Your implementation of attrgetter() looks good. One possible disadvantage of pure functional approach is that attrgetter() will be not a class. Unlikely someone subclass attrgetter, but it can be used in an isinstance() check. You solve this issue.

The same approach can be applied to itemgetter().
