ObjectId("4d6e43c970953cc4bf43b8cc")

> db.test.insert({a:a})

> doc = db.test.findOne()

        "_id" : ObjectId("4d6e43d170953cc4bf43b8cd"),

        "a" : ObjectId("4d6e43c970953cc4bf43b8cc")

> doc.a.equals(a)

true

> doc.a.toString() === a.toString()

true

> doc.a === a

false

> doc.a == a

false

> db.version()

For example, PHP driver works great with it:

<?php

$id = new MongoID();

$sameId = new MongoID((string)$id);

var_dump($id == $sameId); // bool(true)

var_dump($id === $sameId); // bool(false)
