Every program defines a function that maps input from the external world 
(possible null, but not for a game) to output to the external world 
(presumable not null, certainly not for a game).  So defining internal 
function objects is not that big a step.

I agree that creating new classes is a big step, and that using 
callbacks can be a mind-twister.
