What about using iterable type instead of array ? It will allow to return generators or custom result set implementations

I think we will have to wait for doctrine/persistence 2.0 to do this since the Doctrine\SkeletonMapper\ObjectRepository\ObjectRepositoryInterface class implements Doctrine\Common\Persistence\ObjectRepository which returns an array.
