Hmmm. Actually, as Meikel noted, this should be fine, and it does
indeed work for me:
(ns your-namespace
(:require clojure.contrib.io))
The only time I got the "Don't know how to create ISeq from:
clojure.lang.Symbol" exception is when I erroneously copy-pasted and
tried to evaluate this:
(ns your-namespace
> (:require clojure.contrib.io))
