You probably already know this but in Scala with SBT sub projects and incremental compilation you get a very snappy dev cycle (clean builds will always be much slower than Java). I believe the 22 tuple limit is gone in the 2.11 release (in next week or so); if not there's Miles Sabin's Shapeless library (https://github.com/milessabin/shapeless).

Glad to hear you're still going strong, 42 here and can't imagine stopping anytime soon ;-)
