Why Not a Function #13: deep-merge-with

(defn deep-merge-with [f m1 m2] (deep-merge m1 m2 :with f))

deep-merge-with is just a concise way of calling deep-merge with a function as the first argument.

(deep-merge-with + {:room {:chairs 3, :table 1}} {:room {:chairs 1}})
=> {:room {:chairs 4, :table 1}}
