Consider the following function that adds two numbers exceptionally inefficiently by creating lots of threads:
user=> (require '[clojure.core.async :refer [thread <!!]]) nil user=> (defn thread-add [x y] #_=> (thread #_=> (if (zero? y) #_=> x #_=> (let [t (thread-add (inc x) (dec y))] #_=> (<!! t))))) #'user/thread-add This works for small numbers: user=> (<!! (thread-add 10 10)) 20 user=> (<!! (thread-add 10 1000)) 1010 Unsurprisingly, it fails after a certain point, because the JVM simply can't create enough threads. But what I find surprising is that it fails completely silently - no error message, just a nil return: user=> (<!! (thread-add 10 2000)) nil Is this what I should expect? Is there any way to persuade the REPL to show me errors in this kind of situation? -- paul.butcher->msgCount++ Silverstone, Brands Hatch, Donington Park...
