TypeScript Version: 2.0@RC
Code
// Current definition of `Object.freeze`:
// freeze<T>(o: T): T;
const o = Object.freeze({a: 1});
o.a = 2; // Should throw type error
console.log(o); // {a: 1}Expected behavior:
Frozen object has readonly properties
Actual behavior:
Type system allows me to write to o's properties
