Use the source, Luke. http://code.google.com/p/clojure/source/browse/trunk/src/jvm/clojure/lang/LispReader.java?r=1287#656 It looks like the reader reads the whole syntax-quoted form, and then walks it recursively looking for unquote forms. --Chouser --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
