I think it will be a good idea to take a little pause with syntactic additions and other "cognitively loaded" changes. On the other hand, I think it is fine to work on performance improvements (start-up time, import system etc.), internal APIs (like simplifying start-up sequence and maybe even C API), and polishing corner cases/simplifying existing constructs (like scoping in comprehensions that many people find confusing). IOW, I think the PEP should describe precisely what is OK, and what is not OK during the moratorium. -- Ivan -------------- next part -------------- An HTML attachment was scrubbed...
