I understand, but it's still a limitation of arrow functions that they rely on arguments.callee to self-reference. Relying on the defined name they're assigned to suffers from the "can be redefined" problem. NFE's don't suffer this problem and can completely avoid `arguments` in ES6 for all use cases Arrow functions, currently, cannot.
