Shouldn't there be a matching Doc change somewhere? Somewhere is the question!

While None/NotImplemented/Ellipsis are all documented as singletons, the behaviour of calling their types is not specified anywhere. If this was to be detailed anywhere, then the sections on None/NotImplemented/Ellipsis in section 3.2 of the language reference would be the place.

And on that note... was there any particular reason for leaving NotImplemented out for this change?

Cheers, Nick.
