Yes for using __future__, but no for builtins  while it would make things
easier, it is not something that is actually built into python and would be
installable for PyPI via the future package ( So I had to hand define the shims,
though I mostly went for

python2 -> python3 shim such:
if sys.version_info > (3,):
    xrange = range
    raw_input = input

as I dislike overwriting builtin functions/variables if I can avoid it as
it leads to potentially surprising behavior, though reversing that would
not be very difficult if so desired.
