Hi,

Maybe it's worth to write a PEP to summarize all your changes to
optimize CPython? It would avoid to have to follow different threads
on the mailing lists, different issues on the bug tracker, with
external links to GitHub gists, etc. Your code changes critical parts
of Python: code object structure and Python/ceval.c.

At least, it would help to document Python internals ;-)

The previous "big" change (optimization) like that was the new "type
attribute cache": addition of tp_version_tag to PyTypeObject. I
"documented" it in the PEP 509 and it was difficult to rebuild the
context, understand the design, etc.
