// The shebang above associates the file to V on Unix-like systems,
// so it can be run just by specifying the path to the file
// once it's made executable using `chmod +x`.

// Note that you can also use: `#!/usr/bin/env -S v crun`, if your system supports the -S flag to env
// The benefit is that in this case, v could be anywhere in your path, while /usr/bin/env is guaranteed
// to be present on most Unix systems in that exact place.
