use is internal to the current namespace. You can use other namespaces without their publics being added to the current namespace. So: => (ns a) => (def x 10) => (ns b (:refer a)) => x 10 => (ns c (:refer b)) => x java.lang.Exception: Unable to resolve symbol: x in this context You can see that just because b refers to a, it doesn't mean that c gets x by referring to b. This is usually what you want, as you don't want your namespaces to be cluttered up every time you call use or refer. However, for libraries with lots of namespaces, sometimes you want to group very specific namespaces into more generic packages, and that's what immigrate does: => (ns a) => (def x 10) => (ns b) => (immigrate 'a) => x 10 => (ns c (:refer b)) => x 10 - James --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
