this is useful for cases when the for loop is empty and means the developer does not need to create an additional if statement.

e.g.

<% for x in items %>
    <% onfirst %>
        <ol>
   <% onlast %>
        </ol>
   <% onloop%>
        <li>item: <% x %></li>
    <% else %>
    there are no items.
<% end %>

        </ol>
    <% onempty %>
    there are no items.

It applies to while loops as well
