Thing with LLMs, they'll tell you what a great idea and then output a design and tons of code for you which if lack the necessary knowledge will look coherent and correct. It's good to throw the design/code back in and tell them to review it and explicitly prompt them to tell you what is wrong. So here it says your error handling maps directly to POSIX exit code. But then "On success, the function returns a non-zero value." For the sh JIT: The slowness isn't due to the language per se but due to launching multiple processes. If performance is really the goal then you essentially need to replace every process launch with a built-in command. The benchmark is an hallucination unless can indeed be run. Hypothetical benchmarks with hypothetical results are nonsense. (Unless you've a mathematical model backing it up.)
