does anyone knows if there's a way to express getters on js obj in cljs?

{
  a: 1,
  get b() {
    return this.a + 1;
  },
}

Has it been considered to update the implementation of clojure.edn on cljs to support >52 bit integers by using the js/BigInt type? Attached to this is the fact that reading the string 9223372036854775807N using clojure.edn from cljs will produce an incorrect value, even though it's explicitly annotated for being an arbitrary precision integer.
