+1 for getting this into 3.4\. Does it need a PEP, or just a bug
tracker item + code review? I think the latter is fine -- it's
probably better not to do too much bikeshedding but just to let Larry
propose a patch, have it reviewed and submitted, and then iterate.
It's also okay if it is initially used for only a subset of extension
modules (and even if some functions/methods can't be expressed using
it yet).
