    {
        if let anObject: AnyObject = object as? AnyObject
        {
            for obj in self
            {
                if let anObj: AnyObject = obj as? AnyObject
                {
                    if anObj === anObject { return true }
                }
            }
        }
        return false
    }
}

If you have an idea how to optimize this code, than just let me know.
