Actually I've realised the guard won't be invoked on Python 2, anyway: I later
added a "raise ImportError() from e" in an exception handler, which leads to a
syntax error in Python 2 before the guard even gets executed.
So, I'll remove the guard (as it does nothing useful anyway) and think a bit
more about not failing on Python 2. Perhaps - not use the "from" syntax in the
exception handler, and do a no-op in register_hook if on Python 2.

Of course, things like this can be added without too much trouble.
Thanks for the feedback.
