http://clojure.org/ used to have a macro definition of either (and) or (or) somewhere on one of its basic pages. They reorganized it recently though so I can't find it. But yeah, I'm not really sure what Klisp offers over Clojure so far. This sensationalist version of a hello-world isn't really anything new or special so far.

You cannot pass macros as values as they do not exist at runtime. (So no macros can be passed to map/reduce as opposed to the fexprs).

P.D. Msimoni has written about fexprs (and a Lisp dialect with fexprs on JS, wat.js) if you want to read about them some more.

Long ago, when I was learning Clojure, and thought "it's so inconsistent that I can't pass `if` to a function," I would have found fexprs interesting. But I've since thought about it more and realized there's absolutely no need for it at all.
