[$] Faster CPython at PyCon, part one

Two members of the FasterCPython team, which was put together at Microsoft at the behest of Guidovan Rossum to work on major performance improvements for CPython, cameto PyCon 2023 to report on what theteam has been working on-and its plans for the future. PEP 659 ("SpecializingAdaptive Interpreter") describes the foundation of the current work, someof whichhas already been released as part of Python 3.11. Brandt Bucher, whogave a popular talk on structural pattern matchingat last year's PyCon, was up first, with a talk on what "adaptive" and"specializing" mean in the context of Python, which we cover here in partone. Mark Shannon, whose proposed planfor performance improvements in 2020 was a major impetus for this work,presented on the past, present, and future of the Python performanceenhancements, which will be covered in part two.
