I have restarted the work on PEP 3154. Stefan Mihaila had begun an

multiple roadblocks which prevented him to finish his work by the end of the
summer. He previously shown

This seems like an attractive idea. There's definitely a need for repeated

the pattern is suboptimal (not least from the point of view of caching structs).

Thank you for reviving this :)
