Yeah, you see, you can think of a single good reason, although you then contradict yourself just to make it clear that it's not the case. I mean, is there really any good reason why namespace qualifing "deftest" should be necessary. Reason -- it's familiar and there are not that many functions in clojure.test. Another good reason, I have given before. I have written hundreds of lines of code, with *no* calls at all to clojure.core, and lots to my own library. Why under these circumstances is using clojure.core by default and requiring my own library conducive to clear code? > Not much justification you can give me that'll make it unbad.

You can make a function available (require), you make it usable by it's name (use), you can make it available by it's namespace (refer), or you can make it available to another name (aliasing). The changes suggested do nothing toward reducing these things. As you say, you will still able to do all of them. New people will find be introduced to "use" in the repl and find no equivalent in the ns directive. And lots of people will have to replace ":use" directives with something else which does the same, but is longer.
