(async () => {

  // MAIN EXECUTION/SETUP GOES HERE

  const replServer = repl.start({
    prompt: ">> ",
    useColors: true,
    preview: true,
  });
  const historyFile = path.join(process.env.HOME ?? "", ".node_repl_history");
  replServer.setupHistory(historyFile, (err) => {
    if (err) console.warn("Failed to setup history:", err);
  });

  // SET UP CONTEXT TO BE AVAILABLE IN THE REPL
  // replServer.context.thing = thing;

})().catch((err) => {
