Recast is an experimental Smalltalk application that intercepts runtime exceptions, sends the stack trace, method source, and receiver state to an LLM, verifies proposed patches in a shadow Pharo VM, and hot-swaps the corrected method into the live image. It's an intriguing exploration of self-healing software, leveraging Smalltalk's live object model to connect LLM-proposed repairs to a real deployment mechanism.

Target audience: backend devs, researchers, language-runtime enthusiasts
