I'd like to learn a modern production-ready functional language (I have some academic experience with SML), since they seem like a good way to grow as a programmer. Main contenders so far are Haskell, Scala and Clojure (Reason might go on the list soon too) - but the fact that Clojure is dynamically typed is a bit of a turn off for me. My experience with dynamic vs static typing is that as a system grows in size and complexity, the value of static typing goes up. Doing a major refactor is one of those things that I find especially error-prone in dynamic languages, while statically typed languages make this much less daunting (of course they come with the opposite issue that you might not be able to compile for a day until you've fixed all the type errors - but I'd take this trade-off any day of the week). Can anyone with experience comment whether Clojure suffers from this too or if it somehow handles the lack of static typing better than other dynamic languages?
