Hi, I'd like to be able to natively execute Javascript code on MongoDB via Mongoid / Moped

Here's a simplified example of what I'd like to do:

var cursor = #{ criteria.query.xxx ? }
if (cursor.count < 100) { cursor } else { [] }

• criteria.query.xxx represents the serialized Javascript string for my Mongoid query criteria which I've passed-in via string interpolation, i.e {{db.customers.find( {"name": "bob"}

  )}}.

• The result should be serialized into Customer objects in Ruby.

Is this possible to do? (I'm using Mongoid 3 at the moment)
