Hello Eric, our iterators have next() and valid() in separate functions. That alone makes them way more powerful then java' iterators. In SPL we have an iterator wrapper called CachingIterator that has a method has_more() which has a boolean return value that allows to check whether a call to next() leaves the iterator valid or not. So changing the name would only add confusion.
