This triggered a thought.

Given we have std::vector and boost::array, why are move_ptr<T[],D> or even
scoped_array, shared_array even needed?

Do xxxx_ptr< std::vector<T> > and xxxx_ptr< boost::array<T,N> > cover all
use cases.

Are the latter safer, clearer and just as efficient as the former?

The boost Guidelines says:

"Use the C++ Standard Library or other Boost libraries, but only when the
benefits outweigh the costs.  Do not use libraries other than the C++
Standard Library or Boost. See Library reuse. "

Thoughts?
