Description

A BATCH like this

BEGIN BATCH
  INSERT INTO foo (id, num) VALUES (42, 11);
  INSERT INTO bar (id, num) VALUES (42, 11);
APPLY BATCH;

Should not only return [applied]=false, id=42, num=11 but also for example the index of the failed statement in the batch. This allows better error handling on the client.
