Yeah, if you ever get a chance to build something for production in Haskell / Scala / OCaml you'll realize how little even Go (which is better than Python and Ruby!) does for you. The funny thing is, I believe (from real-world startup building experience) that Haskell has allowed me to iterate / prototype my products faster than I ever would have with Python and Erlang (my old go-to tools). Also, with Haskell, there's no late-night and weekend fires to put out :) Which makes me more productive and generally happier.
