I am pretty sure that clojure.tools.reader.edn is a version of the Clojure
reader specifically for the edn subset, hence the name of the namespace.

That said, no need to add a separate dependency on clojure.tools.reader if
you would prefer to avoid it, and you are reading EDN inside Clojure on the
JVM.
