Agreed, it was a HUGE improvement over callback soup. The only cleaner methods I’m familiar with are CSP (as implemented in clojure and go, and to some extent in JavaScript with libraries like RX and Bacon). Basically you’re treating steams of events as first-class values. That’s a rather functional/mathy way to treat concurrency/parallelism but I’ve found it illuminating.
