My point is I don't know what that means. The variable is the binding changing the binding by throwing away the old one is not distinct from mutating it because the binding "isn't a real thing, just conceptual", just as the variable isn't "a real thing"; unlike a value which is actually a thing sitting in a memory slot in your vm. If you can give me an example of where there is a meaningful distinction between the variable and its lexical binding I am happy to be enlightened.
