I highly doubt he's trolling. In his own words from a post where he asked people to refrain from language wars: "Haskell is a tremendously ambitious and inspiring language, for which I have the highest respect. There is zero point in bashing it (or its users) in this forum." Clojure very deliberately adopts the stance that type systems like Haskell's are valuable but heavyweight, and chose development speed and concision over types.
