Generated code appears to omit necessary parentheses

In the Playground,

function makeFn
  => x: 1, y:1

compiles to

function makeFn() {
  return () => {x: 1, y:1}
}

but the latter does not compile as TypeScript (or JavaScript, unless I am mistaken). I believe it needs to be

function makeFn() {
  return () => ({x: 1, y:1})
}
