Using an unstable language may not be a good idea for you. You might be better off learning a different lisp like scheme or newLisp. But you should probably state what you want to do- you said you want to explore, but what are you exploring?. Do you want to write scripts in lisp instead of bash? Are you trying to write a specific kind of program?
I have to recommend avoiding newLisp; it's actually a very old-fashioned Lisp and most likely an evolutionary dead-end. Clojure is another new Lisp dialect that seems like it's worth a look. It runs on the JVM, which could be a big win in the short-term.
First I just want to play. With what I would play? Yes, do what I do in bash would be a good idea. I'd also like to program things for my website. I have ideas of how some things should be on the web but I cannot implement them.
