Recursive data structure using template won't compile

[Rob T]

I want to create a simple recursive data structure as follows:
struct R
{
   int value;
   d_list!R Rlist;
}

// d-linked list with templated payload
struct d_list( T )
{
   struct node
   {
      T payload;
      node* pred;
      node* succ;
   }
   node* head;
   node* tail;
}

The compiler complains about node having "forward references".

I was able to get something like this to work in C++, so I 
imagine I can also get it to work in D, but does anyone know how?

I also want to template the recursive structure itself to specify 
the value type, ie struct R(T){ T value; d_list!R Rlist; }, but I 
left that out to keep the example more simple.

I've been stuck on this problem all day, so any help is 
appreciated!
