[$] Speeding up CPython
Python, at least in the CPython reference implementation, is not a
particularly speedy language. That is not at all
surprising to anyone who has used it—the language is optimized for
understandability and development speed, instead. There have been lots of
efforts over the years to speed up various parts of the interpreter,
compiler, and virtual-machine bytecode execution, though no comprehensive
overhaul has been merged into CPython. An interesting new proposal could
perhaps change that, though it is unclear at this point if
it will take off.
