Sorry, back to this stuff again. I tried using discard inside but #?(:clj #_'whatever) just throws CompilerException java.lang.RuntimeException: read-cond starting on line 32 requires an even number of forms" when compiling on clojure. Would be nice to have a way to ignore reader conditional forms or the thingie things inside but there does not seem to be an easy way. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
