If async and this had been in Py3 from the start, they could've done a far better argument saying "hey, we broke all this stuff, but you get asyinc I/O and faster dicts" (a note of faster dicts: since many classes and language mechanisms use dicts, it should have an encompassing effect on all of python performance -- maybe not 30% or 40% faster, but a few % all around, which is kind of what micro benchmarks are showing with 3.6 betas)
