Tortoise, Hare, Hell, None

[Clarence]

Five and a half years ago, Tim Peters (glory be to his name) made the
following statement:

In that respect, None is unique among non-keyword names, and for that reason
alone it should be a keyword instead of a global. I expect that will happen
someday, too. But it's a race between that and hell freezing over <wink>.

We now know who won.
