http-kit AsyncChannel and clojure.core.async.impl.channels.ManyToManyChannel
Could you explain me why after
clients;; => {#/0:0:0:0:0:0:0:1%0:60071> true}
(into {} clients) ; => #
I get
How {#/0:0:0:0:0:0:0:1%0:60071>
true} is transformed to #?
I suspect it is because I use AsyncChannel as a key, but what is going on?

Re: http-kit AsyncChannel and clojure.core.async.impl.channels.ManyToManyChannel
Sorry, but you guys didn't understand the problem.
*tbc++*, I don't use core.async, so I don't require it
dgrnbrg, I don't want to interface these libraries together.
Let me try explain again.
1. I have http-kit socket server running
2. When client connects I store its connection (http-kit's AsyncChannel) in
map @clients as a key, line 19 (swap! clients assoc con true)
3. Then when some data received from client line 21-22
(on-receive con (fn [data]
(handler)))
I invoke handler
(defn handler []
(future (let
[merged (merge {} @clients)]
(println merged)) ; => #, but expect to get
copy of @clients
#_(let
[into-map (into {} @clients)] ; here I get exception
When trying use into I get I get exception.
I just want to know what is going on, why I get ManyToManyChannel instead of
@clients map copy?

Re: http-kit AsyncChannel and clojure.core.async.impl.channels.ManyToManyChannel
Now it makes sense. Thank you
