In fact I fiddled with the macro just because '#(@%) by itself at my REPL just echoed itself. But this does work: user=> (prn '#(@%)) (fn* [p1__6544] ((clojure.core/deref p1__6544))) So does temporarily clicking off pretty-printing at the REPL and just evaluating '#(@%). On the other hand, the macro's argument doesn't need to be quoted, so there's one less awkward-to-type punctuation character. :) -- You received this message because you are subscribed to the Google Groups "Clojure" group.
