I would say the real solution, the one which increases readability the most, is to remove the need for many parentheses at all by using optional significant whitespace – see http://www.dwheeler.com/readable/ http://www.dwheeler.com/readable/ for an example of such a syntax. (Of course, if you don't export your code to normal, over-parenthesized Lisp before giving it to others, they will have trouble running it.)
