Yes & no.

If your 'nodes' are an extension of Stores.Store the
traversing is done for you, and all you have to do
is write a simple (ie not directly recursive)
Externalize for your node.

Traversing a list by hand is easy enough to do yourself.
Where Stores is clever is that it can handle arbitrary
reentrant net structures. This is a great saving in
complexity and reliability for saving/copying complex
dynamic data structures.
