Yikes. Well, first of all, you need to (map #(str/split % #",") some-seq-of-strings) -- map takes a function and then one or more sequences or collections to iterate over. Further, the function needs to have an argument; with #() closures you use % to stand in for the element from the sequence. So (map #(* 2 %) ox) in your case would return (2 4 6 8) as a lazy sequence. Lastly, though, ox doesn't contain strings so str/split can't be used on them. And I don't know why you had a "reduce" in there. -- Protege: What is this seething mass of parentheses?! Master: Your father's Lisp REPL. This is the language of a true hacker.
