This, 100%. I’ve rewritten some hydrology code in rust using codex sol to first a) profile and create comprehensive tests of the python, b) create full benchmark suites, c) create full scientific benchmark suites, then d) port to rust using a few different techniques.

It works, it’s at least 5x faster, sometimes much more, and memory use is like 10x less and even less in cases where lots of map tiles are involved.

This shit rules.

What I’m wondering now is can we reliably evolve python and have codex act as an extremely unreliable transpiler to the rust.
