In Lisp it makes sense to allow binding keywords because there's no such thing
as a keyword: once you bind it, it's a variable and you can refer to it. In JS
it's impossible to refer to it as a variable so it's just an (un)attractive
nuisance.
The only place where I could see this being arguably useful in ES6 is:
// foo.js
export function function() { }
// main.js
module foo from "foo";
foo.function();
But that's still probably not advisable, since it means you can't import the
name:
import { function } from "foo";
// d'oh
So I don't see any reason why a person shouldn't just use rebinding for that
use case:
// foo.js
function function_() { }
export { function_ as function };
To wit: I say leave it out.
