It is PEP 505.
I agree we should resume the discussion on this PEP though (for 3.7), I'm not completely sure why it stalled.

As Zach and MRAB mention, this was discussed last year. If I recall
correctly, the discussion fizzled out without a solid conclusion. I
think there's a PEP -- if not, there should be.

I would be interested in revisiting this idea, but 3.6 feature freeze is
only a day or two away and I won't have time to discuss this before
then. So let's please drop this discussion until the 3.6 beta is
released.
