skybison VS RustScript2

The parent comment is referring to the primary Python interpreter and runtime, CPython, not to libraries. There are of course other Python implementations, but [the only C++ one](https://github.com/tekknolagi/skybison appears to be unsupported.

Kind of! In my fork I run microbenchmarks on each PR. So you can see on, for example, https://github.com/tekknolagi/skybison/pull/456, that the change had a 3.6% improvement on the compilation benchmark. If you expand further, you can see a comparison with CPython 3.8. Unfortunately Skybison is still on 3.8.

This is also the pointer tagging scheme from the Ghuloum paper. I did not design it. Another tagging scheme I did not design is the Skybison scheme, which uses 0bXXX...XX0 to tag integers and 0bXXX...001 to tag heap pointers. This makes heap reads very easy (bias by -1 in addressing mode).

Skybison is a Python interpreter and I'm curious what the results look like. We also have some benchmarks in benchmarks/benchmarks.

If you take a look at the Skybison Python runtime, I would be happy to chat and help you poke around integrating it: https://github.com/tekknolagi/skybison

I am, in fits and starts, writing a bytecode optimizer for Skybison that takes advantage of type information.

I'm working on https://github.com/mkhan45/RustScript_v2. Of course you can tell from the name it's a bit of a joke but I started writing it just to learn OCaml but I made so much progress so quickly and soon I'll implement a few web server builtins so I can rewrite my personal website in it.
