var read = pull.values([1, 2, 3]).pipe(markable)

var revert = read.mark()

read(null, function (end, data) {
  console.log(data) //=> 1
   //data = 1
  read(null, function (end, data) {
    console.log(data) //=> 2
    //revert takes us back to 1!
    revert()
    read(null, function (end, data) {
