NoneType and new instances

[python at bdurham.com]

Hi Terry,

> Ethan's proposal was accepted on python-ideas. In Python 3.3, the classes for the singletons None, Ellipsis, and NotImplemented will be callables that return the singleton.

Thanks for sharing this news. Its motivating to see this type of
feedback loop because it encourages others (myself included!) to become
more involved in the process.
