 * `defrule` now defines rules as functions with two arities, no args returns the rule map, and 2 args is the compiled RHS.
 * `clojure.lang.Fn` now implements `clara.rules.compiler/IRuleSource`, and returns a single rule by invoking the like `(a-rule)`.
 * add built-in support to serialize `clojure.lang.Var` so that a rule handler var can be serialized correctly.
