An obvious question that arises is what the definition of iterable is.

Is it something for which HasProperty(obj, @@iterator) returns true?

Is it something for which GetProperty(obj, @@iterator) returns something 
other than undefined?

Is it something for which GetProperty(obj, @@iterator) returns a 
callable object?

Something else?
