Proxy error function does not cause unreachable/terminate thread

export const FATAL = (code: ErrorCode) => {
    error('Fatal error occured: ' + code);
};

const some_function = () => {
  FATAL(ErrorCode.FATAL_BAD_SERVER_RESPONSE);
  print('asdfgghjlk') // not marked unreachable
}

const some_function = () => {
  const [ok, data] = // call remote function, if ok = true data is not unknown
  if (!ok) FATAL(...);
  print(data.some_key); // data is of type 'unknown'
}

const some_function = () => {
  const [ok, data] = // call remote function
  if (!ok) error();
  print(data.some_key); // no error
}
