I knew of this functionality when I wrote Domainiter and in fact, earlier I
was using "position" function only. However, it has few drawbacks:
- one cannot change strides, order etc. without changing array
- if one wants to iterate only over block of an array, then first create a
RectDomain, then create an array, etc. It is too complicated
- One may extend DomainIter class to stl complaint iterators. Whereas, use
of
"position" function in stl algos is impossible
