Lambda function with object literal generates invalid ES6 code

[saschanaz]

Orginal TS code:

var a = () => <Error>{ name: "foo", message: "bar" };
/* OR */
var a = () => (<Error>{ name: "foo", message: "bar" });

// I think parentheses should be required here
// Both give same compilation results anyway

d.ts:

declare var a: () => Error;

ES5 result:

var a = function () { return { name: "foo", message: "bar" }; };

ES6 result:

var a = () => { name: "foo", message: "bar" }; // This is not an object literal anymore
