If the truth were, conservatively, 1/4 of new Python code in 2.7, or
even less, I would still be in favor of making 3-friendly 2.7 code easier.
This is also important for the separate codebase approach, as in the
stdlib. Just last week, I got a rejected chunk when backporting because
a 2.7 idlelib module uses 'file(...' instead of 'open(...'.
