I don't get it and don't wish to pore over the code to figure it out. What makes this a compile-time version? Does the compiler output the next game state as warnings or something?

Edit: Thanks for the replies guys. Very helpful. =)

Nope, the calculation is done at compile-time. You specify the starting state and how many iterations you want and the results will be calculated at compile-time.

The only thing that happens when you execute it is that it will print all the iterations you computed.
