I wish I had this much confidence in any one language. I'm productive with Python, but it lacks many useful things and I'm no longer comfortable with the rampant mutation. I like Haskell and the type system is extremely useful (typeclasses ftw), but I haven't managed to become productive using it. Scala scares me like C++ does, through sheer size. Rust is very interesting, but not yet mature enough. I'm not even certain that level of abstraction would generally be the one I want. Clojure is perhaps the closest (especially with core.typed and ClojureScript), but the dependency on the JVM is unpleasant for me to say the least.
