Subject: "999 is enough for anybody" triple-zero padding (#18)

When I hit 999 exercises, I will finally have reached the ultimate
state of soteriological release and no more exercises will be needed.
The cycle will be complete. All that will be left is perfect quietude,
freedom, and highest happiness.

+// The "switch" statement lets you match the possible values of an
+// expression and perform a different action for each.
+//
+// This switch:
+//
+//     switch (players) {
+//         1 => startOnePlayerGame(),
+//         2 => startTwoPlayerGame(),
+//         else => {
+//             alert();
+//             return GameError.TooManyPlayers;
+//         }
+//     }
+//
+// Is equivalent to this if/else:
+//
+//     if (players == 1) startOnePlayerGame();
+//     else if (players == 2) startTwoPlayerGame();
+//     else {
+//         alert();
+//         return GameError.TooManyPlayers;
+//     }
