      "WhatsUp": "E",
      "DragonsExist": false,
      "MonkeysSmart": true
    }`))
  ...
  ast, err := validator.Parse(".WhatsUp == "E")
  ...
  // creates memoizing validator that increases in speed the more it is used.
  mem, err := validator.Prepare(ast)
  ...
  valid, err := validator.Validate(mem, data)
  ...
  if valid {
    fmt.Printf("the serailized json contains a field WhatsUp with a value E\n")
