Built-in ES2015 support

[sindresorhus]

Would be nice to support ES6 built-in at runtime by using the Babel require hook.

That way you can just write your tests in ES6 and have it run in any node version.

This is so nice:

test(t => {
  t.ok();
  t.end();
});

May be use flag --esnext?

{
    "scripts": {
        "test": "ava --esnext"
    }
}

I was thinking ES2015 support by default. Can't think of any reason not to want ES2015 when there's no setup cost.

It would be better then with flag.
