@mfikes this is closed https://dev.clojure.org/jira/browse/CLJS-2413 and I can find the cljs.core.specs.alpha ns but it does not appear to be used anywhere. what is the status of this? is this supposed to be included manually?

@thheller Yes. (The only place this is documented currently is https://clojurescript.org/news/2018-03-26-release#_core_specs_alpha)

Ah thanks.
