And all I can think is that all of this would be more elegant in scheme. In particular, scheme's cut macro makes it practical to re-order args, as opposed to implementing the % expansion used here. And it composes. Or you could always just used readtables to implement your own version of the Clojure lambda shorthand. I'm not clear on why Steve didn't do that. It's a more effective alternative to implementing the % syntax in every macro.
