I'm seeing plenty of xslt-based ways of classing the last unordered list list item, but how to do so in razor? In particular, classing the razor snippet in the distro:

@inherits umbraco.MacroEngines.DynamicNodeContext
@{ 
  var level = String.IsNullOrEmpty(Parameter.Level) ? 1 : int.Parse(Parameter.Level); 
  var ulClass = String.IsNullOrEmpty(Parameter.UlClass) ? "" : String.Format(" class=\"{0}\"", Parameter.UlClass); 
  var parent = @Model.AncestorOrSelf(level);
  if (parent != null) {
    <ul@Html.Raw(ulClass)>
    @foreach (var item in parent.Children.Where("Visible")) {
      var selected = Array.IndexOf(Model.Path.Split(','), item.Id.ToString()) >= 0 ? " class=\"selected\"" : "";
      <li@Html.Raw(selected)>
        <a href="@item.Url">@item.Name</a>
      </li>
      }
    </ul>
  }
}
