Well. Sometimes we want to get the querystring passed into a swf like: someswf.swf?a=1&b=2
But we have to use a DisplayObject.loaderInfo to access the parameters. This makes some functions in a configuration class very “weird”, something like:
public static function getParams(displayObject:DisplayObject):Object
{
var param:Object = {};
param = displayObject.loaderInfo.parameters;
return param;
}
We HAVE TO pass a displayObject inside 
So this is the only way?..
