How would a game loop work?

[Ian Leigh]

What strikes me about rev is that it's harder to manage a flow of 
things from a main loop. For example, a game might have a particular 
loop for overall control which steps through all the required stages 
and then draws a new frame, starting the whole thing off again. How 
would you best manage a game in rev? Would you have a loop off a 'start 
game' button which could only be interrupted by the quit action? Just 
wondering how others have approached laying out games and such 
programs?
