I would just define a function anonymously within the addListener
call, then it has access to all those variables in the scope. This is
probably my favorite thing about event programming in JavaScript vs.
C++. Granted, if you look at the email I sent you can see that it can
get a little out of hand when you start nesting the event handlers. It
would probably work if you defined the function within the calling
function, JavaScript scoping is funky like that.
