**Current behavior** The following code throws error ("Forbids calling `subscribe` without an accompanying `takeUntil`") in the current version: ```ts @Component() class Test { #destroyer = new Subject(); public ngOnInit(): void { someStream.pipe(takeUntil(this.#destroyer)).subscribe(); } } ``` **Expected behavior** The `#` prefixed variables can be used within `takeUntil` when `prefer-takeuntil` rule is enabled.
