> "views" of the data without copying. The current alternative is to use
> Smart Iterators. The advantage of a view is that the data looks to a user
> like a STL container. Stack, queue, and priority queue have a similar
> pattern. Views are built mostly from either a transform_view, or a
> filter_view or a series of both in layers. For example, downcast_view is a
> transform_view using a dynamic_cast to the derived class, then a
> filter_view to skip the zero elements, then another transform_view to
> promote the pointers to references.
