Rails: fields_for with index?
Is there a method (or way to pull off similar functionality) to do a `fields_for_with_index`?

Example: 

    <% f.fields_for_with_index :questions do |builder, index| %>  
      <%= render 'some_form', :f => builder, :i => index %>
    <% end %>

That partial being rendered needs to know what the current index is in the `fields_for` loop.
