> I guess also economic incentives, there hasn't been an incentive for anybody to staff a 50 person project to build a Python JIT given that it's cheaper to rewrite some or all of the application in C/C++/Rust/Go whereas that's not an option in Javascriptland.

From the project README
An excerpt from the repository, fetched Nov 13, 2026.
Read the project’s introduction
Pyston is a faster and highly-compatible implementation of the Python programming language.
This is the old repository for Pyston v1, which has been superseded by Pyston v2
To reduce confusion this repository is kept empty, but if you want to see our old v1 code it is all under the v1.0 tag in this repository.

3 sourcesDropbox's implementation of python was pyston: https://github.com/dropbox/pyston
But I think it's dead now: https://blog.pyston.org/
In Our journey to type checking 4M lines of PythonIt's basically meaningless when you try to line languages up with that sort of criterion.
Go compiles fast enough that you can use it with a wrapper "interpreter": https://github.com/erning/gorun
So does C: https://github.com/ryanmjacobs/c
So does Haskell: https://stackoverflow.com/a/8676377
So does f#, via `#!/usr/bin/env fsharpi --exec` I think
You can compile python: https://github.com/dropbox/pyston
You can compile JS: http://enclosejs.com/
I wouldn't be surprised if someone found a way to AOT-compile bash, but I'm not going to bother looking for that.
The only criterion I've found which makes some sort of sense is whether the language designers consider "scripting" a use case to actively support and use to drive language features, or if it's a second-class citizen.
