Why would anyone want pointer arithmetic for a shared_array? ;-)

I can understand the motivation behind scoped_array (std::vector too
inefficient, presumably) - although I've never encountered a situation where
std::vector doesn't work adequately.

But shared_array? Or going even further, a hybrid container/iterator
shared_array with pointer arithmetic? I find it hard to justify.
