In the spec draft, missing exposing of Symbol.{ dispose, asyncDispose }

[zloirock]

Like here:

That causes such issues: nodejs/node#48699

I don't think this is the cause of node having the wrong descriptors here, to be fair, but it's certainly an omission.

[zloirock]

The current spec has nothing about the descriptors of those symbols (but it should be for consistency with all the rest), so it seems it's the cause of this issue.

[ljharb]

The original implementer in node wasn't looking at the spec either way, they were just adding the Symbols.

[zloirock]

As an option.

[rbuckton]

I can add these to the proposal spec, though the intent was to emulate the exact same behavior we specify for every other built-in symbol on Symbol.

Maybe this is related to typechecking the Playwright project by using tsc --noEmit. I get a bunch of errors:

node_modules/playwright-core/types/types.d.ts:16639:11 - error TS2339: Property 'asyncDispose' does not exist on type 'SymbolConstructor'.

16639   [Symbol.asyncDispose](): Promise<void>;
