AFAIK boost::multi_array (no _ref suffix)  owns memory, but it still does 1 heap allocation.
Yes.

What I have in mind, however, (as I mentioned already ealier) is some general adapter class

template
struct array_index_adapter { ... };

that can apply different types of indices (row major, column major, triangular ...) to different containers (stack allocated, heap allocated, mixed like boost::small_vector etc).
