The best part is that the sub-arrays don't all need to be the same size.

#declare A = array[3];
#declare A[0] = array[4];
#declare A[1] = array[9];
#declare A[2] = array[16];

and if you don't know how big they are, e.g. you've got some macro that fills
them for you, you can just do

#for (I, 0, 2)
 #declare N = dimension_size(A[I], 1);
 #for (J, 0, N-1)
  // do mad pov stuff with A[I][J]
 #end
#end
