================

If your language works like this by default..

var x = {a: 5};
var y = {a: 5};
x === y; // => false

..you're fighting insanity..

var x = {a: 5};
var y = x.a;
y.b = 4;
x === y; // => true
x.b; //     => 4

..and don't let an unfamiliar syntax trick you..

(let [x {:a 5}
      y {:a 5}]
  (= x y)) ;; => true

..because simplicity isn't about syntax..

(let [x {:a 5}
      y (assoc x :b 4)]
  (= x y)) ;; => false

..it's about minimizing the gap between your brain and the problem.
