while that is true, it is possible to program unicode correctly in
python 2 while remaining compatible with python 3. (a combination of
"from future import unicode_literal" and properly using the encode and
decode functions.). I would prefer a stripped version of python 3 that
does not support anything that will really conflict with python 2. for
porting purposes only of course. my employer still uses python 2 so
the idea is to force other developers to use something that will force
working on both during the transition without every single one having
to be extra careful to support both versions.
