Hmm, haven't yet but will do. <g>

Shouldn't you have the declarations for Iter<T> and List<T> before your
Node class?
Try what happens if you put the following lines before class Node in your
code:

template<class T> class Iter;
template<class T> class List;

Personally I'm supprised it worked anyhow if your source was as you
described. 
If the definitions of Iter<T> and List<T> come after the Node class they
don't exist as far as the compiler is concerned, unless you declare them
before Node. After that it isn't important where the definition resides.
