  That's a really complicated way of making a nested loop. What's wrong
with the regular way of doing it?

#declare P1 = 0;
#while(P1 < 4)
  #declare P2 = 0;
  #while(P2 < 4)
    ...
    #declare P2 = P2 + 1;
  #end
  #declare P1 = P1 + 1;
#end

  (Note that array indices start from 0, not from 1.)
