Source docstring:

Wraps body as a CPS function that can be returned from a test to
continue asynchronously.  Binds done to a function that must be
invoked once and from an async context after any assertions.

(deftest example-with-timeout
  (async done
    (js/setTimeout (fn []
                     ;; make assertions in async context...
                     (done) ;; ...then call done
                     )
                   0)))

(defmacro async
  [done & body]
  `(reify
     cljs.test/IAsyncTest
     cljs.core/IFn
     (~'-invoke [_# ~done]
       ~@body)))
