fn main() {
  println!("Hello, world!");

Hey! Sorry, I currently don't have plans to support any compiled languages for now.

The various supported scripting runtimes cover 99% of use cases people expect in mask as a command runner.

I'm glad to see rust-script exists to fill this use case though!
