One of the big-ticket items for the upcoming Python 3.13 release is an experimental just-in-time (JIT) compiler for the language;
the other is, of course, the removal of the
global interpreter lock (GIL), which is also an experiment. Brandt
Bucher is a member of the Faster CPython project, which is
working on making the reference implementation of the language faster via a
variety of techniques. Last year at PyCon, he gave a talk about the specializing adaptive
interpreter; at PyCon 2024 in Pittsburgh, he described the work he and others have been doing
to add a copy-and-patch JIT compiler to CPython.
