Yes, +1 for Emacs + paredit! I have one machine that I haven't put
paredit on -- I wrote a quick Scheme script on it the other day, and
it was *so* cumbersome. Once you get used to paredit, you'll never go
back. :-)

Here's an Emacs/paredit tip (my only one!). If you use the #; syntax
to comment out an S-expression in chicken code, it will get messed up
whenever you reformat the parent sexpr (M-C-q). (Emacs thinks the
semicolon is an end-of-line comment prefix, and it adds space between
the hash and the semicolon.) But if you write it as #;;; --- with
three semicolons --- then it will still work correctly, and Emacs
won't break the # and the ; apart when you reformat.
