I'm stumped by the behavior of the following code fragment. Can someone
help me understand what's happening?
*This code*:
(println "Holding:" (:class holding))
(let [t (:class holding)]
(for [x t] (println "here" x))
(for [x t] (println "there" x))))
*Produces this output*:
holding: {:fundname Mutual Fund 1, :value 123.45, :class [{:class sell-me,
:percent 100}]}
class: [{:class sell-me, :percent 100}]
Holding: [{:class sell-me, :percent 100}]
there {:class sell-me, :percent 100}
Why doesn't the 'for' with "here" print anything?
I tried wrapping the fors with a do, but the output was the same:
(println "class:" (:class holding))
(let [t (:class holding)]
(do
(for [x t] (println "here" x))
(for [x t] (println "there" x)))))
Thanks!
