  This would require to caller to store and pass the address of the 
object. Since a different static function would exist for each 
callbackable member of the class, the caller would have to keep and use 2 
items of data. He would presumably wrap them in a class for convenience, 
at which point he would have reinvented most of the work done by Richard 
Hickey's callback class.
