Thanks—this is really good stuff! Not that I expected anything less, but 
it's a happy surprise that it applies so well to graphs. Now I'm wondering 
if I should just use Datomic rather than borrow ideas from it.

One thing I'm convinced of now is that it's OK to assign ids to everything. 
I was cringing at that idea before, because it seems like an unnecessary 
layer of indirection and one more thing that could go wrong. But clearly 
Datomic's approach of assigning every "entity" an id enables some wonderful 
simplicity, since it enables one to very conveniently chain entities 
together. And when basically everything is an entity, that means you can 
chain anything to anything—which addresses the "type headache" I was trying 
to avoid.
