Actionscript 3 :: Combining URLRequest, URLLoader And Complete Event Listener?

when handling data, i always have to write the following:

var dataSourceRequest:URLRequest = new URLRequest("/path/file.xml");
var dataSourceLoader:URLLoader = new URLLoader(dataSourceRequest);
dataSourceLoader.addEventListener(Event.COMPLETE, handleDataSource);

while i can understand the usefulness of these 2 objects and event listener being separate, since they often work with each other i'd like to know if there is a method that will combine them all? the closest i can get is this, but it's a bit pointless/nesting:

var dataSourceLoader:URLLoader = new URLLoader(new URLRequest("/path/file.xml"));
dataSourceLoader.addEventListener(Event.COMPLETE, handleDataSource);

what i'd really love would be something that automatically combines the URLRequest, URLLoader and completed event listener like this:

var dataSource:Whatever = new Whatever("/path/file.xml", handleDataSource);
