I would like to thank everyone who responded to me for their civilised
and courteous replies. I actually expected to get a lot of slagging
off, but was prepared to accept that for what seemed to me at the time
to be a legitimate concern.
If my fears were unfounded, I am delighted.
If I have been unfair to Guido and the other developers (and it seems
that I probably have), I apologise.
Thank you.
FWIW:
I am not against the PEP.
I do not have a personal axe to grind, in the form of my own pet
idea which I want to see incorporated.
I don't like the .name syntax (grit on Tim's monitor; does not
suggest the meaning). Nor am I keen on "expressions" being interpreted
differently after 'case' than elsewhere in Python. But I don't know
what syntax (where necessary) to suggest.
I'm not keen on special treatment of the '_' variable, and would
prefer to be able to use 'else:' after 'match'.
Best wishes

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 :)
