Usage:

switch(RUNSHELL."java --help") {

    case RunShellResult.Fail(var exitCode, var stdout, var stderr) -> {
        out.println(exitCode);
        out.println(stdout);
        out.println(stderr);
    };
    case RunShellResult.Err(var e) -> e.printStackTrace();
}

switch(RUNSHELL."java -x 2>&1") {
    case RunShellResult.Ok(var stdout) -> out.println(stdout);
    case RunShellResult.Fail(var exitCode, var stdout, var stderr) -> {
        out.println(exitCode);
        out.println(stdout);
        out.println(stderr);
    };
    case RunShellResult.Err(var e) -> e.printStackTrace();
}
