In my current and in my last 2 jobs I've been using a Lisp (Clojure). Since learning Clojure and functional programming in general, I made a conscious choice to seek it out for the last two positions (a small startup and a huge government project) and in this current one (university research) I'm starting two projects from scratch and get to decide myself which language to use, so of course I'm gonna choose the one I enjoy the most and will be more productive in. It's hard to go back to imperative/oop.
