ecmascript 6 - access first argument of call() method of the ES6 arrow function -

is there way access first argument of call() method of es6 arrow function?

var obj = {   getfn: function() { return () => {       //how access bar here       return this.what;     }   },   any: 1 }   var foo = obj.getfn(); var bar = {   any: 2 };  foo.call(bar); 

i'm not sure trying do, if asking how access this value passed via .call, answer is: you can't.

since arrow functions don't have own this, there nothing .call set value to. if want function have own this value, don't use arrow function.
