There are certainly lots of good reasons not to include reader macros in the Clojure (e.g. it raises the bar significantly for people writing editors and other tools). But it would be useful if someone were to maintain a fork of Clojure that adds reader-macro capability, and let the community play with it for a while: sort of the way that the bleeding-edgers are playing now with protocols and deftypes on the 'new' branch. The experimentation might bear some interesting fruit.
