:) nice question gets nice answer!
here it is..
var target:* = Application.application;
var methodName:String = "getChildren";
var type:XML = flash.utils.describeType(target);
var paramLength:int = type.method.(@name ==
methodName).parameter.length();
var f:Function = function(...args):*
{
var tmp:Array = args;
tmp.length = paramLength;
return target[methodName].apply(target, tmp);
};
Alert.show(f("a", 1, 2, 3));
