the movement routine would return a list of any of these side effects:

{new_position, Coordinates} 
{ate_ghost, GhostName}
{ate_dot, Coordinates} 
ate_fruit
killed_by_ghost

All of a sudden things are a lot simpler. You can pass in the relevant parts of the state of the world, and get back a simple list detailing what happened. Actually handling what happened is a separate step, one that can be done later on in the frame. The advantage here is that changes to core world data don't have to be painstakingly threaded in and out of all functions in the game.
