Isn't iterator() the exception from this rule, being the "extension" of
the stream? I would naturally presume the *same* iterator is returned
for the given stream, so this will still be the valid code:

 Stream<T> stream = ...;
 T first = stream.iterator().next()
 // ...many, many lines of code...
 T second = stream.iterator().next()
