The problem i currently see is that most polyglot-projects are reimplementing
the same helper functions (for dict access, literals wrapping etc), not
depending on six because the authors don't feel it's "worth the extra
dependency", as they never need the full functionality of six.

So how about including a subset of six' more popular functionality into the
standard libraries of Python 2 and 3? I think it would solve the problem i
described (i.e. remove boilerplate for polyglot code), while it would also
avoid compromising the builtins of Python 3 (and keep polyglot code "explicitly
ugly")

Also, that's why people demanded a Python 2.8... so that you don't have to
pollute Python 3 instead.
