[$] Making CPython faster

Over the last month or so, there has been a good bit of newssurrounding the idea of increasing the performance of the CPythoninterpreter. At the 2021Python Language Summit in mid-May, Guido van Rossum announcedthat he and a small team are being funded by Microsoft to work with thecommunity on getting performance improvements upstream into theinterpreter-crucially, without breaking the C API so that the ecosystem ofPython extensions (e.g. NumPy) continue towork. Another talk at the summit lookedat Cinder, which is a performance-oriented CPython fork that is used inproduction at Instagram. Cinder was recently released as open-sourcesoftware, as was anotherproject to speed up CPython that originated at Dropbox: Pyston.
