Checking out clojure.core/destructure and clojure.core/let might be
helpful.
Here's a macro I hacked together. It doesn't work with :keys, :as,
or :or. I take no responsibility if you use it for anything real. But
maybe it will provide you with some ideas.
(defmacro destructure->map
[bvec val]
`(let [~bvec ~val]
(-> {}
~@(for [s (remove #(= '& %) (flatten bvec))]
`(assoc (-> (quote ~s) name keyword) ~s)))))
Example:
(let [v [1 2 [3 4 5 6 7 8]]]
(destructure->map [a b [c d & e]] v))
=> {:e (5 6 7 8), :d 4, :c 3, :b 2, :a 1}
