> Calling {{next()}} on an {{ObjectRange}} iterator returns {{null}} when {{hasNext{}}}
returns false.  It should throw {{NoSuchElementException}} to adhere to the Iterator contract.
> {code}
> class ObjectRangeItrTest extends GroovyTestCase {
>     void testItr() {
>         def itr = ('a'..'b').iterator()        
>         assert itr.next() == 'a'
>         assert itr.next() == 'b'
>         assert !itr.hasNext() 
>         shouldFail(NoSuchElementException) {
