Normal PicoLisp has a lot built-in: database, Prolog, web server, and lots more at less than 600K for the OpenWRT distribution. The MiniPicoLisp distribution, sans all the libraries, is only 73kB. It is a very well-thought Lisp geared for decades for practical web and database applications. Check the rosetta code entries for it to compare to other languages, simply amazing!
