Looks like scala/scala#9452 is doing it's thing?

@som-snytt @SethTisue any thoughts? I can silence the warning, but I think this might be a (new) false positive.

@som-snytt wdyt? seems likely that scala/scala#9452 is the relevant PR

hmm, so, it's seems odd or even gross to me that whitespace and comment are defined as Parser[Any]. it's not clear to me if someone was being lazy there, or if there was some trouble getting the ancient version of Scala this stuff was originally written in to use a better type, or what.

Whether it could be improved, and what the compatibility implications of fixing it would be, is something a volunteer could look at.

Assuming Any stays, I think it's plausible this isn't a false positive, given that def | [U >: T](q: => Parser[U]): Parser[U] is in play.

I haven't necessarily thought my way to the bottom of this, but I don't want to spend more time on trying to be certain, since my hunch is that the warning is correct.
