LLVM's opt is very effective. I had a bug in my compiler such that it didn't compile all side effects, and opt removed the entire program!

I've had good results by prompting an LLM "review your changes" in the same session when I don't like the initial output. I'm surprised this is effective: I would think it's redundant when you're running with a high effort setting.

Improve your prompts with better examples rather than better instructions

I really like "zero cost abstractions" as a programming language motto. It's really effective for evaluating design decisions. I've heard it for both C++ and Rust. Are there other PL mottos that are equally helpful?
