Yeah, I am really having a hard time seeing what the fat arrow syntax even changes. Everyone keeps saying scope, but the scope is and always has been lexical, right? That isn't changed. All that seems to be changed is what "this" is. So we got a whole new syntax for locking the value of "this". I agree, that does not seem worth it. There are no mental hoops to see that in "self.foo()", "self" was defined 5 lines up.
