    # mechanism: the state view rendered for <tt>state</tt> will be cached as long
    # as you (or e.g. an EventHandler) calls #dirty!. It will then be re-rendered
    # and cached again.
    # You may override that to provide fine-grained caching, with multiple cache versions
    # for the same state.
