I totally forgot to publicly congratulate Yury on this PEP. He's put a huge effort into writing the PEP and the implementation and managing the discussion, first on python-ideas, later on python-dev. Congrats, Yury! And thanks for your efforts. Godspeed.On Tue, May 5, 2015 at 4:53 PM, Guido van Rossum <guido@python.org> wrote:I now plan to go back to PEP 484 (type hints). Fortunately in that case there's not much *implementation* that will land (just the typing.py module), but there's still a lot of language in the PEP that needs updating (check the PEP 484 tracker).The acceptance is provisional in the PEP 411 sense (stretching its meaning to apply to language changes). That is, we reserve the right to change the specification (or even withdraw it, in a worst-case scenario) until 3.6, although I expect we won't need to do this except for some peripheral issues (e.g. the backward compatibility flags).I've given Yury clear instructions to focus on how to proceed -- he's to work with another core dev on getting the implementation ready in time for beta 1 (scheduled for May 24, but I think the target date should be May 19).I've been following Yury's efforts carefully and I am fully confident that we're doing the right thing here. There is only so much effort we can put into clarifying terminology and explaining coroutines. Somebody should write a tutorial. (I started to write one, but I ran out of time after just describing basic yield.)Everybody,In order to save myself a major headache I'm hereby accepting PEP 492.
