module.exports = and ES6 Module Interop in Node.js

The question: how can we use ES6 modules in Node.js, where modules-as-functions is very common? That is, given a future in which V8 supports ES6 modules:

• How can authors of function-modules convert to ES6 export syntax, without breaking consumers that do require("function-module")()?
• How can consumers of function-modules use ES6 import syntax, while not demanding that the module author rewrites his code to ES6 export?

@wycats showed me a solution. It involves hooking into the loader API to do some rewriting, and using a distinguished name for the single export.

This is me eating crow for lots of false statements I've made all over Twitter today. Here it goes.

// set-up a connection between the client and the server
var socket = io.connect();

// let's assume that the client page, once rendered, knows what room it wants to join
var room = "abc123";

socket.on('connect', function() {
   // Connected, let's sign-up for to receive messages for this room
   socket.emit('room', room);
});

var cluster = require('cluster');

if (cluster.isWorker) {

  console.log('Worker ' + process.pid + ' has started.');

  // Send message to master process.
  process.send({msgFromWorker: 'This is from worker ' + process.pid + '.'})

  // Receive messages from the master process.
