I've just realized there's a really obvious problem with this scheme, which shows it's not really so easy. What if you don't want parens on a line? What if we try to write the identity function? defn identity [x] x This is interpreted as: (defn identity [x] (x)) Whoops! Python and sweet-expressions avoid this by adding () everywhere you want an actual function call. defn my-rand [x] rand() Yuck! Ruby and Perl, which allow paren-less calls do so by basically being the equivalent of a Lisp 2. Haskell deals with it by currying. Maybe use the infix notation to work around it? defn identity [x] |x| This is already getting bothersomely complicated. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
