Cargo-mutants:zombie: Inject bugs and see if your tests catch them

This seems like a near perfect use of coding LLMs and a useful way to implement reinforcement learning.

“Add a major bug to this file that is not covered by existing tests” vs “Find the bug in this file” vs “write a sensible test in this file that protects against this type of bug”

Somehow that reminds me of how diffusion models are trained.

I'm pretty sure that's the premise for GANs (generative adversarial networks) rather than diffusion. Diffusion is more about noise reduction than pitting models against each other
