Hello,

I've come across this amazing library and found a possible bug on Python 3.2. I found this in a django extension which is tested by Travis against 2.7, 3.2 and 3.3 and on 3.2 the tests fail because of an SyntaxError in future/utils/init.py.

Traceback (most recent call last):
...
  File "/home/travis/virtualenv/python3.2/lib/python3.2/site-packages/future/utils/__init__.py", line 419
    return isinstance(obj, type(u''))
                                  ^
SyntaxError: invalid syntax

This only occurs on 3.2 as you can see here https://travis-ci.org/pboehm/django-data-migration/builds/16821855 . For me this looks like a weird error because I couldn't see and error in this line ...
