Array has fixed size and does not implement collection interfaces, such as Iterable, Collection, etc. Also there are 8 primitive specializations of array, and neither is a subtype of Array<T>.
Generally working with arrays is a pain (though not as much pain as in java ;), so they should be used only when there are sufficient reasons to do so.
