However, what if there is no enclosing function? Shouldn't this say 
"enclosing environment"?

If yes, what would be the expected behavior of an arrow function that 
references `this` and `arguments`?
I assume in case of `this`, it would just resolve to the *thisBinding* 
of the environment (if there is one). Since there is no `arguments` 
binding (by default) I assume accessing `arguments` would throw a 
reference error.

Is my understanding correct?
