The syntax shouldn't be trying to second guess whether or not calling close() is necessary or not - it should just be calling it, period.

But *why* should it be called? Just as calling close() after the iterator has finished shouldn't do any harm, *not* doing so shouldn't do any harm either, and some implementation strategies (my current one included) would have to go out of their way to call close() in that case. -- Greg
