Are there any test cases which verify behaviour both in the presence
and absence of certain "from __future__ import" statements?

My first thought would have been simply to write two test files,
one of which imports from __future__ and the other which does not,
and check that in both cases input(x) == eval(raw_input(x)).  

Or is the issue how to test when the input comes from stdin?  In
that case, doesn't faking sys.stdin work as usual?
