Both `for` and `doseq` support the same vector form preceding a body. `for`
returns a lazy sequence and is often appropriate for a purely functional
body. `doseq` is not lazy and returns nil, so it is only appropriate when
you want to run the body for side effects.
Take a look at http://clojure.gi
Hi,
How about this?
> (map-indexed (fn [i x] (vector x)) (for [x (range 10)] "HELLO WORLD"))
(["HELLO WORLD"] ["HELLO WORLD"] ["HELLO WORLD"] ["HELLO WORLD"] ["HELLO
WORLD"] ["HELLO WORLD"] ["HELLO WORLD"] ["HELLO WORLD"] ["HELLO WORLD"]
["HELLO WORLD"])

How does that work: you appear to be iterating over two, unconnected,
vectors.
And yes that's an example of the second option but doesn't explain if or
why that's the best approach- which was the question ;)
