One feature I've seen in ndarray ( for
multidimensional arrays is a template parameter indicating the number
of dimensions which are contiguously stored in row-major order
(  This permits
matching algorithm striding using compile-time dispatch where
possible.  I always thought using a signed template parameter would
permit tracking the analogous column-major guarantee by reversing the
sign.  If the template parameter was 0, then no promises are made
about its contiguousness.
