Simple doseq problem

[Piotr 'Qertoip' Włodarek]

user=> (doseq [word ("one" "two" "three")] (println word))

Throws java.lang.Exception: Unable to resolve symbol: word in this
context.

Could you please give any working example of doseq? I've seen one or
two examples on the web but they doesn't seem to work.

The problem here is that the list ("one" "two" "three") tries to
evaluate "one" as a function. Try this:

user=> (doseq [word (list "one" "two" "three")] (println word))
one
two
three
nil

Or simply quote the list

user=> (doseq [word '("one" "two" "three")] (println word))

Or better yet, just use a vector, please. It's more idiomatic Clojure

(doseq [word ["one" "two" "three"]]
(println word))

Quoted lists are an ugly part of Lisps that can be avoided in Clojure.
I don't see a lot of use for them other than in macros and other
code-producing code.
