    Description

      We are writing a simple ORM for python called maroon. (http://github.com/nod/maroon) Our library builds mongo queries dynamically from python code that looks like this:
      results = Things.find((j==3)&(k>10))

      Right now we have to treat equality as a special case when we do ands and ors:
      db.things.find({j: 3, k: {$gt: 10} });

      It it would make our code simpler and more consistent if $eq was an operator. For example:
      db.things.find({j: {$eq: 3}, k: {$gt: 10} });
