Oh, I still have a long queue of optimization ideas that I want to try
:-) But first, I would like to fix the issue blocking all significant
optimizations: make the stable ABI usable to allow to change major
CPython design choices without breaking C extensions.
Sadly, I didn't find time yet to write a proper PEP for that.
