Hi David,
I am experiencing run-time issue with core.match and core.async
versions:
[org.clojure/clojure "1.6.0"]
[org.clojure/clojurescript "0.0-2411"]
[org.clojure/core.match "0.3.0-alpha4"]
[org.clojure/core.async "0.1.346.0-17112a-alpha"]
Here is my code:
(def c (chan))
(put! c :loaded)
(go
(match (<! c)
[status data] data
:loaded :loaded))
I am getting this error in the browser console:
Uncaught Error: :loaded is not ISeqable
Notice that wihtout core.aync it works fine:
(match :loaded
[status data] data
:loaded :loaded)
