A fait accompli.
The PEP is still a draft and has not been accepted. Don't worry, the normal process is still happening :) Having a reference implementation is a HUGE help, because people can play around with it. There's a fork running an interactive playground so you can go right now and get a feel for the way the syntax works. The implementation has *not* been merged into the CPython trunk. It's not a fait accompli - it's a tool to help people evaluate the proposal (and all of the different variants of the proposal as it evolves). Speaking with my PEP Editor hat on, I would be *thrilled* if more proposals came with ready-to-try code. Only a very few have that luxury, and a lot of the debating happens with nothing but theory - people consider what they *think* they'd do, without actually being able to try it out and see if it really does what they expect. Having a reference implementation isn't necessary, of course, but it's definitely a benefit and not a downside. Also, there HAVE been proposals with full reference implementations that have ended up getting rejected; it's not a guarantee that it'll end up getting merged. Hope that lessens your fears a bit :) ChrisA _______________________________________________ Python-Dev mailing list -- python-dev@python.org To unsubscribe send an email to python-dev-le...@python.org https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/python-dev@python.org/message/E5U5Z6RRWSWHGXTZEQ6CBPORVXS3CPWD/ Code of Conduct: http://python.org/psf/codeofconduct/
