It gives no extra functionality, just syntactic sugar. It lets you 
define your collection of handlers in a single module file, using 
standard function definitions:

function onStartup() ... end

function onShutdown() ... end

etc.

On the other hand, the events onKeyPressed() and onMouseClick() (and 
friends) look like they should apply to some interface object. In that 
case, they could simply be normal object methods.
