This allows for a more declaritive syntax that will make functional programmers
smile:
results = client.add("bucket").map_values_json().reduce_sort().reduce_limit(10)

I made aliases for all the mapred_builtins.js functions to allow for a more declarative style of querying:
result = client.add("bucket").map_values_json().reduce_sort().reduce_limit(10)
I found this to be really handy with search:
result = client.search("bucket", "title:Obama").map_values_json().reduce_sort("""function(x, y) {
// sort by reverse cron
if(x.pub_date == y.pub_date) return 0;
return x.pub_date > y.pub_date ? -1 : 1
}""").limit(10)
