I develop everything (typesetting software, compilers, web server, email client, a desktop environment just for me, a sound synthesizer, my invoice generator, IRC bots, full blown web apps, a wiki engine and tons of general purpose libraries) using Common Lisp. My love for the language comes especially from the fact that its so limitless by design. I have DISASSEMBLE and I have DEFUN. I have ETYPECASE and I have LOOP. Lacking a language feature? Add it with ease and incredible performance.
