You can however use Object.prototype.toString.call() to ensure you are
getting Object’s version of toString(), and not some overridden version:
>>> Object.prototype.toString.call("[object Window]")
[object String]
You can rely on the string between “[object ” and “]” to be the
[[Class]] of the object. (Well, assuming Object hasn’t been changed.)
