Re: Destructuring seems to work with PersistentList and not with PersistentVector

In case it's not clear from the above, {:keys [...]} is a technique for *map* destructuring of associative data structures. (let [{:keys [a b]} {:a 1 :b 2}] [a b]) [1 2] As documented at http://clojure.org/reference/special_forms, :keys takes a vector of the symbols to bind. -- You received
