OOps, I pasted the wrong one here (from the "vec" form)
But looks like I was wrong, and you were correct!!
=> (def k (pr-str (for [x (range 5)]
(do ;(pr x)
x))))
#'user/k
=> k
"(0 1 2 3 4)"
=> (= "(0 1 2 3 4)" k)
true
=> (def k (pr-str (for [x (range 5)]
(do (pr x)
x))))
#'user/k
=> (= "(0 1 2 3 4)" k)
false
