That form means the same as (java.lang.String/getResourceAsStream s) user=> (macroexpand '(java.lang.String/getResourceAsStream s)) (. java.lang.String getResourceAsStream s) That is, a static method getResourceAsStrram of class String. There is no such method because you actually want the instance method of class Call, so you'd get an error. This (or more often its inverse) used to be Clojure FAQ #1 until the (.foo bar) vs. (Foo/bar) interop forms were fully implemented. You should be glad you only run into it now when poking around in macroexpanded internals! :-) --Chouser --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
