Description

initially reported it here(somehow):
https://groups.google.com/d/msg/clojure/T9Kvr0IL0kg/wcKBfR9w_1sJ

Basically clojure.java.io/delete-file doesn't ever return false (even when silently is true, it returns the value of silently), it's due to how it's implemented - but it's obvious from the code, so I'll stop here.

Thanks.

PS: this is what I'm using as my current workaround:
(defn delete-file
"
an implementation that returns the true/false status
which clojure.java.io/delete-file doesn't do(tested in 1.5.0-RC14)
"
[f & [silently]]
(let [ret (.delete (clojure.java.io/file f))]
(cond (or ret silently)
ret
:else
(throw (java.io.IOException. (str "Couldn't delete " f)))
)
)
)

I'm sure you guys can find a better way, but as a clojure newbie(really!) that's what I have.
