Doh!
So, those are the main languages I've played with and developed feelings for recently (within the past 2 years). It's worth noting that there are other languages I left off for brevity. I've also been getting back into JavaScript these days - I have a new appreciation for it's functional nature and closures, and I think JQuery is pretty slick. I've taken a pretty good look at Objective C - it's a decent language but not worth learning unless you want to do a lot of Apple development. I've also played around with Clojure - which is essentially a pseudo-LISP implementation for the JVM - I liked it, but prefer to use 'pure' LISP... though it's attractive being able to write LISPy code that I can run on a JVM, since Java is everywhere. There are a few other languages I haven't had time to take a good enough look at yet but hope to very soon. Specifically, I'm interested in looking at Scala and Caml... and I've begun learning some Haskell and hope to dig into that a little deeper.
