### 💻 Code

```ts
function fooDecorator(originalMethod: any, context: any) {}

export class Symbol { constructor() { } }

@fooDecorator
export class myClass {
constructor() {
const _newSym = new Symbol();
}
}
```

### 🙁 Actual behavior

The generated js code for `myClass` contains
```ts
const _metadata = typeof Symbol === "function" && Symbol.metadata ? Object.create(null) : void 0;
```
Which will access my local variable `Symbol` instead of `window.Symbol`/`globalThis.Symbol`.

### 🙂 Expected behavior

The generated code should access `globalThis.Symbol` in any case or perhaps only if the file contains a local variable (from `class`, `const` or `import`) with a colliding name.

### Additional information about the issue

I found this with an `import { Symbol } from "./service";` call (roughly modelled via this [Bug Workbench](https://www.typescriptlang.org/dev/bug-workbench/#code/PTAEAEDMEsBsFMB2BDAtvAXKAzvATgG7QDG8AdAC7YBQwAVHaABKrSgDKAnqgEYD2sUHWDV4ADwAOfPBVDFYybNg7d+ggN6g5fRNgp4ArsQrSAFAEpQmgL6hr1WmChwkaTKGQSJlGtFRSZKxVeATtQSDw+VFAAIjJgXEISeBiAbgdIA0RjaB1wvj4AEXhiaWQTPFNS3X0jCqwAMSycnUt1eygC4tK8culRSWlZeUVlVE4AYQUlK2otbRrDYzM20Dn5rWq9UAB9SALQAF5QRHgAd2C1C3T5+3sgA)) but this should not change the main problem.

We started to use the class name `Symbol` in our code (and public API) since 2014.

Right now we circumvent this issue by using different names inside the local file via alias names in `import`/`export`
But this is hard to understand and maintain.

Commencez par le playground TypeScript lié et inspectez le code __esDecorate généré afin d’y rechercher la déclaration ou l’importation locale de Symbol. Suivez la manière dont le helper de métadonnées de decorator choisit la référence à Symbol, puis vérifiez que le code émis ne résout plus le binding local et gère toujours l’exemple de decorator présenté.
