rulecljmacro
(rule pattern predicate? consequence)Rule takes a match pattern and substitution pattern, compiles each of these and returns a function which may be applied to a form and (optionally) a success continuation. The function will try to match the pattern and, if successful, and the bindings satisfy the supplied predicate, will call the continuation with the result of the substitution.

rule-simplifierclj
(rule-simplifier & rulesets)Transform the supplied rulesets into a function of expressions which will arrange to apply each of the rules in the ruleset to all the component parts of the expression in depth order, then simplifies the result; the process is continued until a fixed point of the simplification process is achieved.

rulesetcljmacro
(ruleset & patterns-and-consequences)Ruleset compiles rules, predicates and consequences (triplet-wise) into a function which acts like a single rule (as rule would produce) which acts by returning the consequence of the first successful rule, whose pattern-matches satisfy the predicate, or nil if none are applicable.
