It would be nice to be able to ask for a particular ordering for cartesianProduct.

e.g. last range iterating faster, (0,0) (0,1) (0,2) (0,3) (0,4) (1,0) (1,1) (1,2) (1,3) (1,4) (2,0) ...

first range fastest, (0,0) (1,0) (2,0) (3,0) (4,0) (0,1) (1,1) (2,1) (3,1) (4,1) (0,2) ...

expanding N-dimensional surface containing all covered so far
(0,0) (1,0) (1,1) (0,1) (2,0) (2,1) (2,2) (1,2) (0,2) (3,0) (3,1) ...

by n_0 x n_1 x n_2 x ... x n_N chunk
e.g. for a 2 x 2 chunk on a 4x4 set, using first index fastest for chunk
ordering
(0,0) (1,0) (0,1) (1,1) (2,0) (3,0) (2,1) (3,1) (0,2) (1,2) (0,3) (1,3) (2,2)
(3,2) (2,3) (3,3)

See also #9878, especially the discussion linked in comment 2.
