    Yeah, I thought about that, but it seems like you can only use them to get the "map" part of map/reduce... no aggregation. Unless I'm missing something.

    Awesome. If there's a Github issue about it I'd be interested to follow it.

      I just added one -- see https://github.com/rethinkdb/rethinkdb/issues/1118 https://github.com/rethinkdb/rethinkdb/issues/1118.
