Relevant JIRAs

• 1.10.439 - https://dev.clojure.org/jira/browse/CLJS-2913
• 1.10.516 - https://dev.clojure.org/jira/browse/CLJS-3050

[^1]: Due to the way that macros are expanded in ClojureScript, you'll need to configure Expound in Clojure. This does not apply to self-hosted ClojureScript.

(Note the `-e` arg below)

`clj -Srepro -Sdeps '{:deps {expound {:mvn/version "0.8.5"} org.clojure/test.check {:mvn/version "0.9.0"} org.clojure/clojurescript {:mvn/version "1.10.520"}}}' -e "(require '[expound.alpha :as expound]) (set! clojure.spec.alpha/*explain-out* expound.alpha/printer)" -m cljs.main -re node`

Now you will get Expound errors during macro-expansion:

```
ClojureScript 1.10.520
cljs.user=> (require '[clojure.core.specs.alpha])
nil
cljs.user=> (let [x])
Execution error - invalid arguments to cljs.analyzer/do-macroexpand-check at (analyzer.cljc:3772).
