deno bundle: the bundle file does not have the same behavior as the source

[SteelAlloy]

Let's consider these three files:

// three.ts
export let value = "old"

export function setValue() {
  value = "new";
}

// two.ts
export { value, setValue } from "./three.ts";

// one.ts
import { value, setValue } from "./two.ts";

setValue();
console.log(value)

If we run one.ts:

$ deno run one.ts 
new

If we run bundle.js:

$ deno bundle one.ts bundle.js

$ deno run bundle.js
old

The result is different.

Bundled file:

// bundle.js
let value = "old";
const value1 = value;
function setValue() {
    value = "new";
}
const setValue1 = setValue;
setValue1();
console.log(value1);

Tested on:

• deno 1.7.1
• Windows, Linux
