So i've been talking with arbiter about efficiency and he suggested that being able to provide a query with our own data set ie list of npcs to perform the query on would allow for greater efficiency. I can see great potential use for this everywhere and think it would be a nice feature. @Cloud
You could work around this by streaming your data set and filtering it I guess. But it would be nice to see that, maybe an overload of the results() method, where you give your own data set as a parameter.
