/*
 * I bikeshedded a lot on how to do this and I'm still not entirely happy.
 * The main thing is you need a weak ref to the poly because it may be invalidated due to graph updates.
 * I had a struct version but you still need to store the neighbors somewhere, maybe on the chunk itself?
 * Future dev work required.
