In all fairness paulp has been bashing the shizazz out of Scala since his departure.

And yes, he's still involved, but far less so than before when he was working full-time on the compiler at TypeSafe.

On the plus side, Dotty, the new "simplified" Scala compiler, is in the works and collections library will likely be overhauled in the process.

as for Clojure, typed Clojure looks interesting, but otherwise the little rascal Haskell is my Scala escape hatch for the time being.
