I made some far-reaching changes, as I was finding it difficult to include a lot of background while keeping the post size manageable. I settled on having the post talk almost entirely about how we're using / planning to use invariants, and targeting it at people w/ a degree of Datalog familiarity. It doesn't cover too many broader Datopia details that are covered in other posts.
We could have follow-up posts which talk about using
invariantas an independent library when we've got a more solid API or other working examples - the idea with this one is to provoke interest in people w/ the relevant background knowledge.Minor stuff:
