 It still needs some stuff before it's "good":
 
-- A DSL to parse from a string to a datalog program (this would make it way easier to introduce new variables, among other things.)
-- Any level of query plan optimization (in fact right now we definitely have the worst possible performance in a lot of cases.)
 - A sample app
 - Aggregation of any kind
-- Named fields instead of just using positional semantics.
-- Indexes or primary keys of any kind for faster queries
+- Any level of query plan optimization (in fact right now we definitely have the worst possible performance in a lot of cases.)
 - It might not be safe to store databases in the model (that is, it will break the Elm debugger because the Set implementation we use embeds a comparison function. It would be possible to take this out, but would require more effort than I want to make at the moment I'm writing this README.)
-- Warnings for situations where queries might not work the way you expect (e.g. doing `reachable(a, c) :- reachable(a, b), reachable(b, c).` instead of `reachable(a, c) :- link(a, b), reachable(b, c).`)
 - Nice errors that say exactly where the problem is in the query

 I plan to implement those things in roughly that order (maybe adding or dropping a few as I go) and releasing this as an Elm package when it's ready.
