    Description

      Add $position option which takes a positive number.

      db.col.save({_id:1, a: [3]})
      db.col.update({}, {$push: {a: {$each:[1,2], $position:0 }}}) // pushes to front of array

      If $position is equal to or greater than the array size then it will be ignored and is effectively a push to the end, which is the default behavior if not specified.

      This will allow you to effectively $pop from the top and add to the bottom or vice versa using $slice since you push in either direction.
