One annoying point with language_level=3 is that all string literals 
become unicode (like from __future__ import unicode_literals). Unlike 
the other changes that language_level=3 makes, this is a major breaking 
change on Python 2.

So I would very much prefer enabling everything that language_level=3 
does, but keeping strings of type "str" on Python 2. Maybe you could 
invent a new option for that, say "language_level=3str"?
