Yeah, i certainly wouldn't expect it to be able to export the array part.

As far as implying an effect on the environment, i don't know, it obviously
doesn't contradict the documentation or anything, but it seems intuitive (and
useful) to me that it would behave that way. But i realise that would be an
enhancement, not a bug.
