   6 --------
   7 AWK's array is not a first class value - it cannot be copied and passed around.
   8 One of approaches to work around this issue (the other I tried in life-004) is
   9 using a single array with a new element for each generation (so that we can
  10 refer to the previous while building new). Problem is that there are no
  11 multidimensional arrays either...  However, facilities are provided for
  12 simulating them by storing level dimension information in the key of the
  13 associative array, so I ended up with board[generation, x, y] and manually
  14 deleting a generation when it is no longer needed.
