@fatcerberus Yes, there are lots of similar issues (and it seems like a wontfix), but I could not find any work-around (except "as boolean" or "as any" in nasty parenses) about how to rewrite such a code, as a pattern. Is there any?

You found the workaround / pattern already. Using a type assertion here is not a quirk.
