Start Clojure REPL to copy core:
user=>
       (require '[clojure.java.io :as io])
       (spit "resources/cljs/core.cljc" (slurp (io/resource "cljs/core.cljc")))
       (spit "resources/cljs/core.cljs" (slurp (io/resource "cljs/core.cljs")))


Launch ClojureScript REPL:
rlwrap lein trampoline run -m clojure.main script/repl.clj
cljs.user=>
            (load-file "resources/cljs/core.cljc")
            (require 'cljs-bootstrap.core)
            (in-ns 'cljs-bootstrap.core)

            (def e (assoc (ana/empty-env) :context :expr))

            (js/eval (with-out-str (c/emit (ensure (ana/analyze e :foo)))))
            (js/eval (with-out-str (c/emit (ensure (ana/analyze e 3)))))
            (js/eval (with-out-str (c/emit (ensure (ana/analyze e (list [2 3 4] 1))))))
            (js/eval (with-out-str (c/emit (ensure (ana/analyze e '(+ 2 3))))))
            (js/eval (with-out-str (ensure (c/emit (no-warn (ana/analyze e `(first [7 8 9])))))))
