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.

Like shell scripts? Cause I mean, I agree, I think this world would be a better place if starting tomorrow shell scripts were no longer a thing. Just probably not what you meant.

Pretty much agreed - once any sort of complicated logic enters a shell script it's probably better off written in C/Rust/Go or something akin to that.
