This killed it for me: class Callback ..... this.then = g => new Callback(callback => Can't we just keep OOP out of FP?

  Using class enables us to chain instances naturally in JS syntax, especially because JS lacks infix functions or custom operators. o1.then(f).then(g).run(cb)

  You can avoid the class syntax here and write a function to return the same if you prefer.
