Affects version 0.1.8 (but version isn't listed as a valid version in JIRA)
clojure.core.typed refers to clojure.main/repl (line 725 in master)
However clojure.main is not required by the clojure.core.typed namespace, so you get an error if clojure.main has not already been loaded. This can happen in various circumstances, e.g. running "mvn test"
Code to reproduce / fix:
(:require [clojure.main]) ;; this line is needed to avoid an error
(:require [clojure.core.typed :refer [ann inst cf fn> pfn> check-ns ann-form]]))
