"At the heart of Clojure and ClojureScript’s implementation is #equiv that is in turn based off of Henry Baker’s egal operator introduced in this paper. Briefly, equality in Clojure is defined by equality of value, which is facilitated by pervasive immutability. Equality in the presence of mutability has no meaning." http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.23.9999 http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.23.9...
