__future__.barry_as_FLUFL turns x!=y into x<>y.
But the doc by help() says:
Help on _Feature in module __future__ object:                                                                                                                                                                                                               class _Feature(builtins.object)
--snip--
|  getMandatoryRelease(self)                                                                                                  |      Return release in which this feature will become mandatory.                                                            |                                                                                                                             |      This is a 5-tuple, of the same form as sys.version_info, or, if                                                        |      the feature was dropped, is None. 
--snip--

Since <> is dropped, __future__.barry_as_FLUFL.getMandatoryRelease() should be None. But it instead returns (4, 0, 0, 'alpha', 0), which
means it will become default in Python 4 and drop != (!= is invalid
after the __future__ import).
That shouldn't be right.

It was not officially dropped. It was kept as a joke.

It's an easter egg and internal joke. Barry would be disapointed if we would deprive him of his title.

Thanks for keeping the first 'F' in FLUFL!  :D
