Not yet, although I would like to make use of simple maps natural. I had been toying with the idea of typing into the :type metadata that could be attached to a map, allowing expressions like:
(defrule test-rule [:example/person-map-type (= "Alice" (:first-name this))] => (println "Hello, Alice!")) That way any map with that type annotation could be used in the rule. Today Clara does automatically bind "this" as a reference to the matched object, so functions can be called against it. (I'm not particularly thrilled by the implicit binding of "this", but it is common in rules engines so I included it here.) The advantage of records is they have a pre-defined type and pre-defined fields, so they are a natural alternative to facts and slots seen in other production systems. But since simple maps are so common in Clojure code I do want to incorporate them here, either by tapping into the type metadata as seen in the above example, or by doing something akin to how multimethods work, where the fact "type" is effectively defined by a function. I'd love to hear suggestions on this one. The goal is to get the advantages of a production system in a way that feels natural to Clojure developers.
