In the "stride" version, we rather store the "block size" of each dimension, which is akin to the Fortran representation, and the representation (if I understand the chapel representation correctly).


What is "block size"? How is to do with Fortran being column-major/1-indexed? How it an address computed using block sizes? How is non-aliasing ensured?
