Suggestion: listen-chan!

[JulianBirch]

listen-chan! could either set up a listen that writes to a provided channel, or create the channel itself. The latter is more convenient in the usual case, the former is more desirable in the general case.

By channel, do you mean core.async? My only concern is that you then force a dependency on core.async. I think this is simple enough and can be application-specific:

(defn listen-chan! [node event-type]
  (let [c (chan)]
    (dommy/listen! node event-type #(put! c %))
    c))

I do, but my understanding is that any dependency on core.async would be stripped out by advanced optimizations anyway.
