IMHO the correct way of getting an iterator is having the aggregate return it (say, using find_method/invoke); and the iterator does not need to be of class Iterator, it just needs to behave like one. Otherwise your Iterator needs to know all the types it has to iterate over, which is bad. Regards Mattia
