Never mind, I found the patch and the issue. I really think that the PEP is ready for inclusion after the open issues are changed into something like Discussion or Future Work, and after adding a more prominent link to the issue with the patch. Then the patch can be reviewed some more until it is ready -- it looks very close already.

Going over the open issues:

- Parallel arrays or arrays of tuples? I think the API should require an array of tuples. It is trivial to zip up parallel arrays to the required format, while if you have an array of tuples, extracting the parallel arrays is slightly more cumbersome. Also for manipulating of the raw data, an array of tuples makes it easier to do insertions or removals without worrying about losing the correspondence between the arrays. - Requiring concrete sequences as opposed to iterators sounds fine. I'm guessing that good algorithms for doing certain calculations in a single pass, assuming the full input doesn't fit in memory, are quite different from good algorithms for doing the same calculations without having that worry. (Just like you can't expect to use the same code to do a good job of sorting in-memory and on-disk data.) - Postponing some algorithms to Python 3.5 sounds fine.
