MovieClip(parent).function throws error TypeError: Error #1034:

Question

The error says there is a forced conversion of a loader to a movieclip.
I am using a container movie main.swf to load a child movie. The child movie tries to access a variable and a function in main.swf
child.swf contains:
import flash.display.Loader;
import flash.display.MovieClip;
import flash.events.Event;
MovieClip(parent).traceF;
MovieClip(parent).globalVar;
The loader Main movie is movie.swf which has its code in a Main.as doc
package
import flash.display.Loader;
import flash.display.MovieClip;
import flash.net.URLRequest;
import flash.events.ProgressEvent;
import flash.events.Event;
public class Main extends MovieClip
public var globalVar:String = "global";
public var myLoader:Loader = new Loader ();
public function Main()
this.addEventListener(Event.ADDED_TO_STAGE,init);
private function init(e:Event):void
loadFile("child.swf");
private function loadFile(path:String):void
var myRequest:URLRequest = new URLRequest(path);
myLoader.load(myRequest);
myLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loadProgress);
myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);
private function loadProgress(evt:ProgressEvent):void
var amountLoaded:Number = (evt.bytesLoaded / evt.bytesTotal)*100;
trace("Loading: % " + amountLoaded);
private function loadComplete(evt:Event):void
trace("Complete - " + evt.target.content);
addChild(myLoader);
public function traceF ()
trace(globalVar);

If you are loading the swf into another swf using the Loader class, the Loader is the parent of the loaded file.  The parent of the Loader is the main swf you are probably after... MovieClip(parent.parent) from the loaded file's perspective.
