Why is it that although this works:
~~~clojure
(defn foo [& args] (let [{:keys [a b]} args] (str a \~ b)))
;;=> #'some-app.core/foo
(foo :a 1 :b 2)
;;=> "1~2"
~~~
this does not:
~~~clojure
(let [{:keys [a b]} [:a 1 :b 2 :c 3]] (str a \~ b))
;;=> "~"
~~~
?
And even stranger, *this* *does* work:
~~~clojure
;; Changed vector to a list.
(let [{:keys [a b]} '(:a 1 :b 2 :c 3)] (str a \~ b))
;;=> "1~2"
~~~
?
Incidentally, I see that the following `let` also does indeed work:
~~~clojure
(let [ [& {:keys [a b]}] [:a 1 :b 2 :c 3] ] (str a \~ b))
;;=> "1~2"
~~~
Thanks!
