There was a problem hiding this comment.
I don't know if this is actually correct, unless I'm misunderstanding? it seems to me that empty patterns are allowed? https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=755341695f14b8bd2d51f095778ec222
