Isn't a matrix a "rank 2". I'm using the term "rank" because that's an
apl term, and I'm a fan ;) :

Anyway, why not a template:

   template < typename T, typename Shape >
   class array

where Shape is a vector_c<unsigned, S1,S2,...,Sn>

to create a rank n array with S1 is length (or dimension)
of 1st axis, S2 the length of 2nd axis, ... ? The strides
of such a "compile-time specified shape" array could also
be calculated at compile time as shown in the test_partial_product
function of fold_seq_test.cpp in in
