  Maybe. But if it doesn't need to be a delegate, you could tag 
static on it and give it a second go since it's just another 
function at that point. Worse case is it doesn't work. An idea is 
coming to mind to change it all to a struct and build and test 
it, then remove the outer struct when your done, but that's a 
second level of work. Just gotta consider the inner function as 
just another part of the function itself.
