Claude asked me a question today: was I looking for an Emacs plugin (because I was talking about elisp) or a Rust program (because I have configured Rust preferences)? I'm really impressed, it's rare to see LLMs ask follow-up questions. (I wanted Emacs in this case.)

I would have thought that invoking a C compiler would be a solved problem. Looking at Rust's cc crate there's a remarkable long tail of corner cases to fix. Exotic CPUs, microarchitectures, compiler differences, operating system differences, etc. https://github.com/rust-lang/cc-rs/blob/main/CHANGELOG.md

I'm implementing an interpreter, and wondering how often I should check for interruptions (e.g. Ctrl-C). I don't want to spend too much CPU time checking whether I've been interrupted, but I also want slow programs to stop promptly. It's tricky.
