That is not what happens in lein repl: user=> (use 'clojure.core.async) nil user=> (def pingc (chan)) #'user/pingc user=> (def ^:dynamic *text* "OUPS BAD ASYNC") #'user/*text* user=> (binding [*text* "good boy"] #_=> (go (while true #_=> (<! pingc) #_=> (println *text*)))) #<ManyToManyChannel clojure.core.async.impl.channels.ManyToManyChannel@79d236c2> user=> (defn ping [] (put! pingc :ping)) #'user/ping user=> (ping) good boy nil
It's of course up to core.async to preserve bindings within its body. But since it tries to pretend to run your `go` code 'as if it was synchronous', that's probably desirable?
