go-try throws ClassCastException: clojure.lang.Keyword incompatible with clojure.lang.IObj

Trying to use superv.async in my ClojureScript project, but (go-try S ...) throws a ClassCastException at compile time:

(ns myproject.async-test
  (:require [cljs.test :as t :refer (deftest testing is async)]
            [cljs.core.async :refer (go <!)]
            [superv.async :refer (S <? go-try)]))

(deftest my-tests
  (testing "why won't this run?"
    (async done
      (let [ch (go (ex-info "hi" {:data 123}))]
        (go-try S ;; this complains.
          (<! ch)
          (done))))))

Error:

Thanks for reporting! This is strange, it is not obvious to me where this comes from. Which version are you using?
