Github user rxin commented on the pull request: https://github.com/apache/spark/pull/2281#issuecomment-54684308 I'm not sure if that belongs here. The reason is it is an implicit assumption of all APIs. For example, if you add the result of an iterator that reuses object into an array buffer, everything will break. But you don't see that documented in the iterator api or the array buffer api.
