### 💻 Code

```ts
// Arbitrary stand-in for Object imported from 'runtypes'.
// Anything using this name would suffice to trigger the error:
// "Object.getOwnPropertyDescriptor is not a function".
// Replacing "Object" with "globalThis.Object" in the __esDecorate
// emitted by TypeScript fixes the conflict.
class Object {
validate(): boolean {
return false;
}
}

function AnyDecorator(method: any, context: any): void {
console.log('Method decorated!');
}

class Foo {
@AnyDecorator
bar(): void {
console.log('Method called!');
}
}

const foo = new Foo();
foo.bar();
```

### 🙁 Actual behavior

TypeScript emits the decorator helper `__esDecorate`, which refers to `Object`. This is clobbered by an Object class defined in or imported by the module, which leads to the error `Object.getOwnPropertyDescriptor is not a function` at runtime.

### 🙂 Expected behavior

`__esDecorate` should use `globalThis.Object` to avoid this naming conflict. I've confirmed that modifying the compiler output to use `globalThis.Object` instead of plain `Object` fixes the conflict.

### Additional information about the issue

This was discovered when I used decorators with the [`runtypes` library](https://github.com/runtypes/runtypes/), which exports a class called `Object`, used for validating object structures at runtime. The two don't even have to be used together in any meaningful way. They just have to be referenced in the same module.
