ASP.Net MVC RouteData and arrays

Question

If I have an Action like this:

public ActionResult DoStuff(List stuff)
{
   ...
   ViewData[\"stuff\"] = stuff;
   ...
   return View();
}

Combining both methods works nicely.

public static RouteValueDictionary FixListRouteDataValues(RouteValueDictionary routes)
{
    var newRv = new RouteValueDictionary();
    foreach (var key in routes.Keys)
    {
        object value = routes[key];
        if (value is IEnumerable && !(value is string))
        {
            int index = 0;
            foreach (string val in (IEnumerable)value)
            {
                newRv.Add(string.Format("{0}[{1}]", key, index), val);
                index++;
            }
        }
        else
        {
            newRv.Add(key, value);
        }
    }

    return newRv;
}

Then use this method in any extension method that requires routeValues with IEnumerable(s) in it.

Sadly, this workaround seams to be needed in MVC3 too.
