The ‘__future__’ features are language features, and like other features
they do not get added retro-actively to an already released Python
version. So, Python 3.5 has a set of ‘__future__’ features that are the
only ones that will ever be in Python 3.5.

When a feature is added to ‘__future__’ it is to introduce a
backward-incompatible feature gradually, and like any feature is always
added as part of the development of Python versions. So, new features in
‘__future__’ will only appear in *not yet released* Python versions.

In short: To get the changed behaviour, you need a newer Python version.
