Bug Report

The __proto__ in the object literal has special meanings in JavaScript and TypeScript doesn't recognize that.

__proto__

🕗 Version & Regression Information

💻 Code

class X { echo() { return this } }
const y = { __proto__: X.prototype }

🙁 Actual behavior

Type of y is `{ proto: X }

🙂 Expected behavior

Type of y is X

Duplicate of #38385. Literally the first issue after yours when searching for __proto__ (the search term you listed).
