[$] Following up on the Python JIT

Performance of Pythonprograms has been a major focus of development for the language over the lastfive years or so; the FasterCPython project has been a big part of that effort.One of its subprojects is to add an experimental just-in-time (JIT) compiler tothe language; at last year's PyCon US, project member Brandt Bucher gave an introduction to the copy-and-patch JITcompiler. AtPyCon US2025, he followed that up with a talk on "What they don't tell youabout building a JIT compiler for CPython" to describe some of the thingshe wishes he had known when he set out to work on that project. Therewas something of an elephant in the room, however, in that Microsoftdropped support for the project and laid off most of itsFaster CPythonteam a few days before the talk.
