Description
When I use `boost::multi_array` with `boost::fortran_storage_order()`, and I want to `.resize` by only the latest (rightmost) dimension, the current implementation is a nested `N` function call (`std::copy`), one by dimension.
The same functionality can be reached with one `std::copy` on the storage.
