clojure.core/print-method is a multi method that handles the printing of objects. You can override or implement the print method by:
(defmethod print-method my.class.Foo [^my.class.Foo instance ^Writer w] (.write w ....<string>...)) I do that to provide custom printing for deftypes, but you can easily override how records are printed as well.
