1. according to the MongoDB FAQ, collection names can begin with an underscore, but in mongo shell it results in

MongoDB shell version: 1.1.3

> db._a.insert({a: 1});

Sun Nov 29 14:19:16 JS Error: TypeError: db._a has no properties (shell):0

> db._a.findOne();

Sun Nov 29 14:19:36 JS Error: TypeError: db._a has no properties (shell):0

while

> db.a.insert({a: 1});

> db.a.findOne();

{ "_id" : ObjectId("4b1274ce2da8fd0af74f3a1c"), "a" : 1 }

2. When inserting document with PHP driver it works
