Author of Mjolnir here. There's some major updates going on in the "datomic" branch. If you're thinking of using Mjolnir in a project, you'll want to keep an eye on that branch over the next few months.

With Datomic, the inference engine is completely re-written in datalog. This allows for a massive code clean-up, and the code in that branch is much cleaner.
