That example i think is minor mistake. As noted in the example
above you have to call pass ->getIterator() to count(). count()
doesn't detect if the object if getIterator is present, its just
returns 1 since $A isn't an array.
BUT.. this works:
echo count( (array)$A );
Yet, even if you use count($A->getIterator()) or cast the object,
the indexes (0,1,2) arn't defined, unlesss you redifine the
offsetGet() to get the proper one.
