Hi all,
Thanks for taking the time to read my post. I'm interested to get some
opinions from experienced Clojure programmers on whether the language

Judging by the articulateness of your post, I would say that Clojure
would definitely be an ideal language for what you are looking for. It

Interestingly, there's this book which is a crash course on building a
