      conn.update("test.user", BSON("y" << 1), BSON("x" << BSON("a.b" << 1)), true);
conn.insert("test.user", BSON("x" << BSON("y.z" << 3)));

      And end up with a field you cannot refer to on its own:

      > db.user.find()
{ "_id" : ObjectId("51c85fc622cbaa0259719bca"), "x" : { "a.b" : 1 } }
{ "_id" : ObjectId("51c8627822cbaa0259719bcb"), "x" : { "y.z" : 3 } }

> db.user.find({ 'x.a.b': 1 })
> db.user.find({ x: { 'a.b': 1 }})
{ "_id" : ObjectId("51c85fc622cbaa0259719bca"), "x" : { "a.b" : 1 } }

      Note: Currently, some drivers already have checks to prevent user from doing this (test on the mongo shell and Ruby driver). Might also want to consider adding the check on the server.
