Is Ruby supposed to be an example of "not dying" language? Because it has certainly passed its glory days as well. Also Common Lisp is better in every way ;) There's even a JVM implementation (ABCL) for people who like that sort of stuff.
While the community around Clojure is fantastically good, I don't like the language itself as much. Personally for my hacking pleasure, Haskell, Common Lisp, Chez Scheme (or other Schemes), and Ruby are all more fun for me to use.
