If you declare a private attribute has @!items then all your references to that attribute have to include that sigil. If you declare it with the dot sigil: has @.items then it creates an accessor, so that self.items or @.items work for accessing, as well as @!items. You can also declare has @items; in which case a private attribute @!items is declared, with a lexical alias @items (without any twigil). This could become a FAQ entry...
