The problem is that core.async defines some functions which are also
defined in clojure.core. When now you invoke into, you are not referring to
the clojure.core/into but to cosee.async/into which, if I remember right,
takes a channel as first argument.
If you want to use the clojure.core

The question is why that is happening when you load up the repl--are you
using 'use' or 'require' with :refer all on core.async in your p1.core
namespace? If so you should probably switch that reference to something
like
(:require [cljs.core.async :as async])
If this is not what's going on I'm
The repl indicates that current namespace is p1.core
p1.core= (into [:a] (list :b :c))
and I imagine in p1.core is where core.async is used or required + referred

Hi David,
This has been very helpful in understanding the internals of the ClojureScript
compiler and I found it fascinating. Much appreciated.
I am having a bit of trouble understanding the syntax of the user environment
map. Is there documentation for this? My goal is to specify multiple

The docs for unchecked-add (

)
only cover the case of both arguments being primitive longs.

Om/Reagent are wrappers over React.js with slightly different approaches,
and are the bees-knees.
The React.JS rendering approach is a great idea in general, and a great fit
for Clojurescript, and discussed elsewhere:

Hey folks,
At Room Key we're using Apache Zookeeper and a home-grown clojure library
called drcfg for real-time application configuration management. We're
debating open-sourcing drcfg and are trying to gauge community interest in
such a tool.
We think it's got great usage semantics,
FYI atoms backed by zookeeper are already provided in Avout library [1].

RIght - we're familiar with Avout, in fact in the beginning we were using a
(very early) version of Avout at Room Key.

I wanted to see others' opinions on other ways of doing it.
You're seriously overthinking this if it's any more than a one-liner.

To say nothing of y:
yes - one vowel
any - two vowels
but the filter thing is good otherwise.

The best lead I've got thus far is that there is a disj call that returns a
