Thank you for your response. The reasons why I didn't use protocols are following. 1. Currently ClojureScript doesn't have `extend`, which makes inheritance easy. http://david-mcneil.com/post/1475458103/implementation-inheritance-in-clojure
2. I think an entity which is created by deftype or defrecord should represent a value rather than an identity, after reading this article. http://clojure.org/state The methods I implemented need to update an entity value itself. So in order to follow immutable manner, the methods should return a return value and an updated entity itself. This programming style is difficult when a method needs to call another method or makes callback which need to update an entity itself. I suspect that to include atoms as fields of record make the entity an identity. Is this wrong? Thanks.
