Rust with Clap solved this forever ago.

Also - don't write CLI programs in languages that don't compile to native binaries. I don't want to have to drag around your runtime just to execute a command line tool.

Well that's confused me. I write a lot of scripts in BASH specifically to make it easy to move them to different architectures etc. and not require a custom runtime. Interpreted scripts also have the advantage that they're human readable/editable.
