For keywords in particular you can write the identifier anyway, r#async is a perfectly reasonable (though ugly) way to use async as an identifier, despite the fact that async is a keyword in current Rust editions.

But the problem is that while we can mechanically perform the operation that doesn't have the effect claimed, it's as if people expected (and I know this does happen with idiots) that Chinese is just the same as English but with different symbols.
