There may or may not be a separation into two passes, that's almost an implementation detail. You can macroexpand a whole top-level expression and then compile it, or else do macroexpansion as to-be-evaluated expressions are compiled. Clojure actually uses the second approach, but you can switch to the first by using clojure.contrib.macro-utils/mexpand-all. And since you can call mexpand-all from a macro, the distinction between the two approaches really becomes blurred.
