      { $push: { a:

      { $each: [ 1 2 3] }

      } }
      is the new $pushAll. The latter will be deprecated in favor of this

      Syntax for creating a fixed sized array is:

      { $push: { a:

      { $each: [1], $trimTo: 5 }

      } }

      I.e after appending the elements in $each, we'd trim the resulting array to 5 elements.
