There was a problem hiding this comment.
I'm trying to think of a reasonable type that could defeat the check but
- No, I just can't think of one thanks to how "properties" on tuples work
- Even if I thought of one, I can't imagine why you'd end up here and feel like you "lost out" on this check.
Even though I'm not a fan of the types that were constructed, @NWilson put it best: it is what it is, and it doesn't look like too much work to revert back to the pre-3.9 behavior.
