It would be nice to have a function throw>! that puts an exception into the
channel and throws it when taken, so that I can write
(let [c (chan)]
(go (throw>! c (Exception.)))
(go (try
(prn (<! c))
(catch Throwable t
(prn "exception")))))
instead of
(let [c (chan)]
(go (>! c (Exception.)))
(go (try
(let [res (<! c)]
(if (instance? Throwable res)
(throw res)
(prn res)))
(catch Throwable t
(prn "exception")))))
