ClojureScript reads records as maps. Bug?

namespace.clj

(ns namespace)

(defrecord Language [name])

(defmacro lang [name]
  (->Language name))

(def clj
  (lang "Clojure"))

;; Clojure reads the emission of the macro as a record

clj
;=> #namespace.Language{:name "Clojure"}

(type clj)
;=> namespace.Language

namespace.cljs

(ns namespace
  (:require [cljs.reader])
  (:require-macros [namespace :refer [lang]]))

(defrecord Language [name])

;; This does not fix the issue below.
; (cljs.reader/register-tag-parser! "namespace.Language" map->Language)

(def cljs
  (lang "ClojureScript"))

;; ClojureScript reads the emission of the macro as a map

cljs
;=> {:name "ClojureScript"}

(type cljs)
;=> cljs.core/PersistentArrayMap
