#TIL that an array of arrays has its own name: Iliffe vector. https://en.wikipedia.org/wiki/Iliffe_vector
Why do we have a name for the naive implementation of multi-dimensional arrays, but don't have a name for the one that uses clever indexing into a one-dimensional array to make it multi-dimensional?
@minoru As I began with fortran my definition of "navie" and "clever" seems to be the opposite with that one of yours.
