Possible unit test, since clojure.string is aliased in the test file:

(is (= (dir-fn 'clojure.string) (dir-fn 'str)))

After poking at it for a while, I discovered that the test in question isn't being executed in clojure.test-clojure.repl namespace, but in user. So replacing the failing test with:
(is (= (the-ns 'clojure.test-clojure.repl) ns))
also fails.

Which is very surprising to me. Is this the expected behavior? I could fix the test by doing the following:

(binding [*ns* (the-ns 'clojure.test-clojure.repl)]
(is (= (dir-fn 'clojure.string) (dir-fn 'str))))

But I don't want to mask an error, if this behavior is unexpected. Guidance please.

You know this could be due to direct linking - calls inside the clojure code to other clojure code are now direct linked (static) calls as of 1.8.0-alpha3 and can't be redef'ed.

Yeah, if you turn direct linking off the test passes.

We've missed the window for 1.8 but it's in the queue for 1.9.
