This examples seems to illustrate this point. In order to qualify a keyword to a namespace, the namespace doesn't actually have to exist, so it really is just a part of the name, in some sense: 1:19 user=> (namespace :foo/bar) "foo" 1:20 user=> (ns-interns 'foo) java.lang.Exception: No namespace: foo found (repl-1:20) 1:21 user=> foo/bar java.lang.Exception: No such namespace: foo (repl-1:21) - J. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
