Michael Fogus has also done some work porting On Lisp to Clojure. Chapters 2-5 are here: <a href="http://blog.fogus.me/tag/onlisp/" rel="nofollow">http://blog.fogus.me/tag/onlisp/</a><p>Halloway picked up where Fogus left off.
I would absolutely <i>love</i> a more advanced Clojure book in the same vein as "On Lisp", especially if Stuart Halloway is in any way involved. Most of the content can probably be pretty similar modulo differences in the macro systems and such (probably have to axe the reader macros chapter...)
chapter 9 is particularly useful. clojure doesn't have hygienic macros, but it does have namespaces, so it is not as likely as common lisp to silently introduce naming problems. that's explained quite well there (better than i have found anywhere else).
