New submission from Raymond Hettinger:
Future imports in a module aren't transferring to the interactive shell when executing Run Module.
Given the file tmp_future.py
----------------------------
$ cat tmp_future.py
from __future__ import division, print_function
print(32 / 5)
Run Python interactively
------------------------
$ python2.7 -i tmp_future.py
6.4
>>> 32 / 5 # this works fine!
6.4
But open the file in IDLE and press F5:
---------------------------------------
Python 2.7.9 (v2.7.9:648dcafa7e5f, Dec 10 2014, 10:10:46)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "copyright", "credits" or "license()" for more information.
>>> ================================ RESTART ================================
>>>
6.4
>>> print(32 / 5) # this is broken!

Note, the problem may also apply to IDLE Python 3.4 and 3.5 but it won't affect this example because the future imports have not effect.
