I use 'use' yes. Take, for instance, this code. It uses my own library to generate a series of logical statements (about pizza's -- there is a reason, daft though it sounds).
https://github.com/phillord/tawny-pizza/blob/master/src/pizza/pizza.clj It isn't until around the 300th line that I first use any of the clojure.core functions (ignoring the 'ns' directive which obviously comes first). Quite often when I use this library, I have to use refer-clojure to switch the implicit clojure.core use off, because it gets in the way; I would do the same thing with java.lang if I could but as far as I can tell those symbols are there regardless of what I do. I would defend this usage of use. I do not want to namespace qualify the tawny.owl library; why should I do this when I have hundreds of calls to this library and about 5 to clojure.core? I'm happy for you to tell me why I am wrong on this. From this thread, I understand I could achieve the same thing with :require and more typing; this is not the point; pulling in one namespace into another sometimes makes sense.
