Asyncio wasn't added until 3.4, so it was hardly the initial thrust of what Python 3k was trying to accomplish. Guido even admits he didn't even understand how Twisted's Deferred's worked until a year ago: https://groups.google.com/forum/#!topic/python-tulip/ut4vTG-08k8 https://groups.google.com/forum/#!topic/python-tulip/ut4vTG-... ... which I think is great that he really took the time and Pep 3156 is the better for it. I still feel like this should have been what Py3K was about though, and not tightening up semantics in the language. Who cares about the semantics? Python has warts but we love it anyway.
