Object.fromEntries: return type does not account for symbols

[mfulton26]

TypeScript/src/lib/es2019.object.d.ts

Line 8 in d2516fa

fromEntries<T = any>(entries: Iterable<readonly [PropertyKey, T]>): { [k: string]: T };

const record = Object.fromEntries([[Symbol.for("1"), "hi"]]);
console.log(record[Symbol.for("1")]);

error: TS2538 [ERROR]: Type 'symbol' cannot be used as an index type.
console.log(record[Symbol.for("1")]);
 ~~~~~~~~~~~~~~~

the return type should account for objects built with symbols for keys (e.g. through a generic type or something)

There's a whole template you're supposed to fill out when you file a bug here, to help the TS team triage and respond.

Anyway I don't think much can be done here until something like #35909 and #26797 are dealt with. Also relevant: #37457, with the comment: "Symbols are still dropped on the floor, just like the rest of the compiler."

Weird, I was never prompted with a template. Maybe that is because I made the issue from clicking the referenced line of code...
