Re: Anyone willing to do a tutorial on minecraft modding in clojure?
Is Bukkit an option? I've used https://github.com/CmdrDats/clj-minecraft. Active project, fun and easy to use.

Re: Help with writing a function to merge two maps
Here's what I came up with:
(require '[clojure.set :as set])
(let [->map-fn (fn [s] (->> s (map (juxt :id :val)) (into {})))
xs-m (->map-fn xs)
ys-m (->map-fn ys)]
(->> (set/union (keys xs-m) (keys ys-m))
(map (fn [k] {:id k :val (* (get xs-m k 1) (get ys-m k 1))}

Re: Destructuring syntax
"Joy of Clojure" adds a second reason for this:
"The second reason is because it allows us to conjure up other
destructuring features by using forms that would otherwise make no sense.
Because the item on the left of each pair will be a new local name, it must
be a symbol or possibly a nested destructuring form. But one thing it can’t
be is a keyword, unless the keyword is a specially supported feature such
as :keys, :strs, :syms, :as, and :or."
