I'll leave most of this to Fred, but I'll reply to two items (Fred canadd these replies to the PEP):> Again on proxies, there is no discussion or documentation of the> ReferenceError. Why is it a RuntimeError? LookupError, ValueError, and> AttributeError seem to be just as fine or better.RuntimeError was my suggestion. The error doesn't really qualify as aLookupError in my view (there's no key that could be valid or invalid)and ValueError seems too general (that's typically used forout-of-range arguments and unparseable strings and the like). Do youhave a reason why RuntimeError is inappropriate?> On to the type type extensions: Should there be a type flag indicating> presence of tp_weaklistoffset? It appears that the type structure had> tp_xxx7 for a long time, so likely all in-use binary modules have> that field set to zero. Is that sufficient?Yes, that should be sufficient. (I'm also going to clain tp_xxx7 forthe rich comparison function slot, but either patch can be modified touse tp_xxx8 instead.) Maybe it's time to add a bunch of new spares?> Thanks for reading all of this message,You're welcome.--Guido van Rossum (home page:http://www.python.org/~guido/)
