Arrow functions don't bind at all this or arguments or anything else they resolve them by lexical scoping. This is interesting:

> Dave said to me, essentially, “The ‘lexical this‘ phrase is troubling, because this has always been lexical.”

What's going on is that => DOES NOT bind this​, because => arrow functions don't have a ​this​ at all! So from there it's lexical scope to find ​this​ which can misinterpreted as some kind of new interpretation (like the ​self = this​ pattern or binding)
More implications:
Arrow ​=>​ can't be called with ​new​ or ​bind(obj)​ doesn't work either
