// This gist aims to explain how it's possible that async functions inside React
// using createFetcher(Promise).next(key) can work.

// A possible implementation of the new createFetcher function
// as shown by https://twitter.com/jamiebuilds/status/969169357094842368
// @param method, should be a function returning a Promise.
// @returns an object with a property 'read', used to read values from the resolved 'cache'.
const createFetcher = function(method) {
  // First create a Map for the resolved values.
  const resolved = new Map()
