Q: How can I elegantly apply a projection to an entire MongoDB collection using Cashbah Assuming that coll is a MongoCollection, I know that I can select all documents by calling coll.find(), and I know that I can apply a projection to all documents by calling coll.find("_id" $exists true, projection) where projection might be something like MongoDBObject("_id" -> 1). Is there a way to do this more elegantly, like (just imagined) coll.find($everything, projection)?

A: An empty document will perform a find all eg:
coll.find(MongoDBObject(), projection)
