I include this in sugar as in: You can refactor an arrow function into a specific regular function but you usually end up with something more verbose. Or in other words you can express all things "arrow" before it existed. Which is exactly what we did before they were adopted. And we still in fact do, just automated by transpilers like Babel[0].
