> Clojure and Haskell might be interesting, but I worry that the non-modifiable memory could bite me in the end For the record, this is absolutely no problem given the generational GC in the Hotspot JVM; the structural sharing in Clojure's persistent data structures generate a little extra garbage, but it's barely a blip on the radar. Laziness can have more of an impact on memory usage, but it's usually really easy to spot.
