[$] Speeding up CPython

Python, at least in the CPython reference implementation, is not aparticularly speedy language. That is not at all surprising to anyone who has used it-the language is optimized forunderstandability and development speed, instead. There have been lots ofefforts over the years to speed up various parts of the interpreter,compiler, and virtual-machine bytecode execution, though no comprehensiveoverhaul has been merged into CPython. An interesting new proposal couldperhaps change that, though it is unclear at this point if it will take off.
