Damn it, you're right. :-)
(try
(async/>!! cf 1)
(catch Throwable e
(println "caught exception")))
catches it.

no, in the same thread. your code is wrong, assert never throws an
exception.

With apologies for spamming:
in case anyone else wanted a solution to this problem:
I believe the right layer is to wrap at the Channel layer, rather than the
Buffer layer: for example:
(ns test
(:require
#+clj [clojure.core.async.impl.protocols :as impl]
#+cljs [cljs.core.async.impl.pr
Consider the following attempt:
for some reason, after the assertion fails, the main repl thread seems to
lock up
Line 1
Line 2 // after this, no more is printed
Question: what is causing the problem -- and how do I fix it?
Thanks!
=== code ===
(ns test
(:require
#+clj [clojure.core.as
Can't you just test the value before placing a value in a channel? 22.01.2014, 16:27, "t x" :Hi,## Question: For a channel, is it possible to put a pre-condition of sorts on a channel? For example: (let [chan (async/chan 100)] (set-pre-condition! chan even?) (put! chan 1) ;; exception thr
