Very nice.  Thanks for sharing.

I really think you should make it available as an egg.  Although s may
not sound very appealing to users who already know the srfi-13 API, it
can still be useful for newcomers that know s and want to get started on
Scheme (or port some code for it) or even for those Scheme users that
for some reason don't like the API provided by srfi-13.

Some random comments:

* procedures from the data-structures unit are usually faster than the
  similar ones ones from srfi-13 (some of them provide similar
  features).  For example, I'd implement s-starts-with? using
  data-structures' substring-index[-ci] instead of srfi-13's
  string-prefix[-ci]?, or string-chomp for s-chop-suffix.

* maybe drop the dependency on the regex egg and use the built-in unit
  irregex?

* if you intend to publish your code as an egg, it would be nice to have
  the documentation in the Chicken Wiki format, so it can be indexed by
  chickadee (http://api.call-cc.org).


Best wishes.
Mario
