 Talking points
 
 - It's hard for Node to conform to Codable, because of references
   - This is a problem in both directions. For encoding, we need to keep track of what we've already seen. For decoding, we need two-phase initialization.
   - But we can convert to sparsegraph, and then we get conformance for free
     - to do this, an iterator over all reachable nodes really helps!
