Interestingly, the feature they said that about (async rewriting in catch/finally blocks) is almost exactly the feature that has been floating around the clojure-sphere as an example of something tremendously complex that was made easier by being more imperative. It's hard to explain how much of a rat's nest something can be without being trapped in it yourself, but "people thought it was impossible to do _at all_, and we were doing it in a purely functional way until we refactored" sounds pretty nuts.
