 ## Motivation
 
-Proposal motivation
+Sometimes operator usage are more declaraive way than function calls:
+
+```js
+const sumOfAges = [{ count: 1 }, { count: 2 }, { count: 3 }, { count: 4 }].reduce((a, b) => a.count + b.count);
+```
+
+I propose to make operator declaration and make operators as a first-class object inside language
 
 ## High-level API
 
 ```js
-// example code
+const (+) = (a, b) => {
+  if ('count' in a && 'count' in b) {
+    return a.count + b.count;
+  }
+  return super(a, b);
+}
+
+const sumOfAges = [{ count: 1 }, { count: 2 }, { count: 3 }, { count: 4 }].reduce(+);
 ```
