is basically PHP embedded in Common Lisp. So any example I give you to show how cool CL-WHO is you could render it in PHP and conclude that PHP is similarly cool.
The Big Win only happens if you want to combine a feature that is best served by language X with some other feature that is best served by language Y. In the non-Lisp world, you now have to start gluing together code from entirely different ecosystems, whereas in Common Lisp everything lives together in the CL ecosystem (including nowadays the ability to call C code). So I can combine CL-WHO seamlessly with other programs written in CL (and C). That turns out to be a huge win in the long run.
It pretty much comes down to Greenspun's tenth rule [1]. Macros and the ability to embed DSLs are a huge win in certain domains. Two which I have personally worked in are autonomous spacecraft control and chip design. You can do things in Lisp that you could not even conceive of doing in C short of, as Greenspun's tenth observes, basically re-inventing Lisp.
