There is Tauthon[1] which backports Python 3 features to 2 and seems to do the "actual work". It has been around a while.
It was also posted in this thread below by the current maintainer of the project but for some reason that comment was downvoted to [dead].
By reading a bit around about it, i do get the impression that the Tauthon developers face a bit of hostility from the Python community, so i'm not sure how viable it'll be in the long term. I suppose it depends on how stubborn the Tauthon developers are :-P
