+life-005
+========
+
+
+Approach
+--------
+AWK's array is not a first class value - it cannot be copied and passed around.
+One of approaches to work around this issue (the other I tried in life-004) is
+using a single array with a new element for each generation (so that we can
+refer to the previous while building new). Problem is that there are no
+multidimensional arrays either...  However, facilities are provided for
+simulating them by storing level dimension information in the key of the
+associative array, so I ended up with board[generation, x, y] and manually
+deleting a generation when it is no longer needed.
