Been rather quite around here lately so I just wanted to do a quick check to see what the status is on PEPs 342 and 343. I noticed Nick's PEP is still not up. Probably too busy with that fix for genexps in the AST branch, huh, Nick? =)

Something like that. . . still, I finally got around to fixing the formatting in the text file and sending it back to David :)
Guido, you need something hashed out from us at this point, or do you have this all settled in your head and are just waiting for time to lock it down in the PEP? Or should the PEPs be changed from draft to final and an implementation (which I am *not* volunteering for =) is now needed?
There's a generator finalisation PEP to come from Raymond, and Guido has made some comments on that front that probably need to be folded into PEP 343.
Yeah, I'm mostly waiting for Raymond to make the changes to PEP 288. I guess the flap over Decimal's constructor (nicely concluded by Mike Cowlishaw -- we should invite him to do a keynote on EuroPython next year) and the uncertainty of the possibility to call close() from the destructor may have slowed that down. I wonder if we can make progress by leaving that final part (automatic invocation of close() upon destruction) out -- I don't think that anything in the rest of the spec would have to change if we can't call close() automatically. If Raymond would rather defer to me, I can give it a shot in a revised version of PEP 343, at the same time as finishing up some other loose ends there (e.g. I'd like to switch allegiance to 'with').
And implementations will probably have to wait for the AST branch anyway. . .
That's fine. But don't underestimate the VM work needed! I looked at what it would take to add an optional argument to <generator>.next() so that yield could return a value, and realized that I don't know my way around ceval.c any more... :-( If people are interested in sprinting on this at EuroPython I could be available for some time, but we'll need someone more knowledgeable about ceval.c to kick-start the work. -- --Guido van Rossum (home page: http://www.python.org/~guido/)
