In any case, if you know how and can implement the __future__ import, that
would be great. Otherwise, valid Python3 code using that import currently
fails to compile in Cython.
In addition, perhaps you should consider adding a compiler directive (or
there is one already that I'm missing?) that we can pass with -X o type as
a #cython comment in sources.
In the face of ambiguity... give users various alternatives to the control
the behavior.
