clojure.browser.repl is accessing the property of an event via the / syntax, which seems to have been deprecated:
https://github.com/clojure/clojurescript/blob/f74b50967ef4041db585bd6c6f2f490285f61961/src/cljs/clojure/browser/repl.cljs#L71
It causes warnings on compile:
WARNING: No such namespace: e at line 71 resources/public/js/bin-debug/clojure/browser/repl.cljs
Attached is a fix
cljs
e/currentTarget also appears inside the clojure.reflect module (reflect.cljs, line 19 - where e is again an event object). Presumably this should also be changed if this style of property access has been deprecated.
Updates another e/currentTarget instance as pointed out by Greg Chapman.
