OK, I am confused by the fact that __builtins__ as a print function that
matches the Python 3.x print function. You can see this doing 
'$ pydoc __builtin__.print' and I believe this is what is confusing
IPython too. What you are saying is that that function does not kick in
if we don't do the __future__ import, right?

Cheers,
