If I took a list, I'd have to make and store a copy of its contents. It would be expensive, and it would not see subsequent changes to the original array. I wanted a lightweight iterator tied to a user-modifiable array.

The user can create an anonymous array and slap an iterator on it, if he so desires: array_iterator(@{[1..10]}). That makes it obvious that this iterator can't give you the free lunch that for (1..10) does.

Caution: Contents may have been coded under pressure.
