How is that enforced - "*must* be a real array"?  Is the diagram in 
Appendix A that shows the "array" that is returned only "conceptual"? 
It implies a ~items and [] method being sent to the "array". So an 
object that implements those two methods, even if not a "real array", 
ought to work in my mind.  And if not, how come?
