Where do I sign up to fight you on that last one? :D

Allowing _ in return position only for private functions feels like something that ends up surprising 99% of people either that this works, or that it doesn't work for their public function and neither group of people are filled with joy as a result.

It's not a hill I'd die on, but it would go on my list of things I don't like in Rust, along with most as casts, impl AddAssign for String, is_ascii_predicates(/* taking */ &self)

The likelihood of it actually landing is quite low, because I suspect quite a few people would agree with you, and as long as rustfix can deal with it I also don't care as strongly about it ^_^
