I think the "trap" here (if there is one) is that coming from another language, you might believe that "doto" is setting some magical "context" value. For instance, the with statement in javascript does some sort of magic to alter the "current scope". If you understand that "doto" is simply a macro that alters the source code that it is invoked upon, it's pretty clear what is wrong with your code. This same understanding then applies to all the other similar macros (.., ->, ->>). None of them are doing anything other than rearranging source code. --Aaron -- You received this message because you are subscribed to the Google Groups "Clojure" group.
