S-lang is a great programming language. And Jed (http://www.jedsoft.org/jed/ http://www.jedsoft.org/jed/) is an extensible text editor using it, and it's a decent and lightweight alternative to Emacs. Bindings are the same, automatic indentation works wonderfully well, and one might prefer S-lang to Emacs Lisp. Jed remains my text editor of choice today, and the first thing (along with ag, zsh and cowsay) I install on a new machine.
