I'm not myself dealing with this, but Armin Ronacher and I were
chatting about this on IRC. He says that for Jinja it is impossible to
maintain 2.x and 3.x in the same code base while keeping compatibility
with 2.4. The result of this conversation is a 2to3 feature request:
Add pragmas to 2to3 that would hint at the correct translation.
