Editing a variable length list, ASP.NET MVC 2-style

A while back I posted about a way of editing a list of items where the user can add or remove as many items as they want. Tim Scott later provided some helpers to make the code neater. Now, I find myself making use of this technique so often that I thought it would be worthwhile providing an update to show how you can do it even more easily with ASP.NET MVC 2 because of its strongly-typed and templated input helpers.
