To the lisp / scheme curious:
I'd suggest installing Racket, opening DrRacket and going through this tutorial: http://docs.racket-lang.org/quick/
You'll be coding fun things in mere minutes... even with no lisp or even *any* programming experience!
Writing a web application is only a few lines away: http://docs.racket-lang.org/continue/index.html
Try it! I promise you'll have fun!
@webshinra DrRacket does some of the nicer emacs parenthesis management things, and even provides a lot of the navigation / structure editing keybindings that paredit does. I was surprised how nice it felt.
@cwebber That's good to know, thank you.
Even if I would not recommand it for a «serious use» (learing a editor per language is a conceptual error IMAO) I'll have no hesitation proposing it for pedagogic use :)
