module.exports = function (context) {
  return { Program() { context.report() } };
};

module.exports = function create(context) {
  return { Program() { context.report() } };
};

module.exports = (context) => {
  return { Program() { context.report() } };
};

  create(context) {
    return { Program() { context.report() } };
