Eric and I spent some time discussing this today, and don't see any
insurmountable barriers to doing it as an import hook. It may mean doing a
2.7 compatible full importlib backport, but that's also useful for other
reasons.

We may also want to consider/discuss integrating this idea with the
python-future project rather than making it a new independent project, as
that provides ready access to Python 3 style builtins that a hook could
inject as globals in flagged files.

Regardless, I think we're now drifting off topic for python-dev - Eric and
I are still at the sprints, so we'll take a look at the feasibility of
proposing this to Ed and the other python-future devs (I also have some
ideas around using sitecustomize to put an entire Python installation into
enforcement mode for flagged files).

Any other related suggestions should probably be directed to python-ideas
at this point.

Cheers,
Nick.
