An great thing about Lisp/s-expressions, overlooked in this article, is that your code is divided hierarchically into little chunks that can be slurped, barfed, cut, paste and rearranged trivially with structured sexpr editors like Paredit or Smartparens. "Take just this subexpression of a larger expression, move it into the parameter list of the function call five lines down" is annoying using almost any text editor with languages like C or Python. It takes about a half-dozen composable keystrokes for sexprs in Emacs with Paredit.
