💻 Code

// @strict: true
// @declaration: true
// @target: es2020

// @filename: a.ts
export const o = {[Symbol.iterator]: 1}

// @filename: b.ts

import { o } from "./a";
export class Symbol { }
export const g = o;

🙁 Actual behavior

The typeof of g is { [Symbol.iterator]: number; }. This leads to an incorrect declaration since Symbol is shadowed in the current scope

🙂 Expected behavior

The typeof of g is { [globalThis.Symbol.iterator]: number; }.
