Applying above suggestions, the first sentence of the entry "__future__" would be replaced by:

A :ref:`future statement <future>`, "from __future__ import *feature* ...", directs the compiler to compile the current module using syntax or semantics that will become standard in a future release of Python. The :mod:`__future__` module documents the possible values of *feature*.

And the confusing sentence, "A pseudo-module which programmers can use to enable new language features which are not compatible with the current interpreter." would be removed.

Can I fix this issue this way? 
If confirmed, I would make a PR for this issue.
