Rust: Suggest parenthesising multiple arguments to dbg!()

[varkor]

fn main() {
    dbg!(5, 10); // error: no rules expected the token `,`
}

It would be nice if the compiler suggested the intended form: dbg!((5, 10)) as this seems like a reasonable mistake. This is specific to a particular macro, though, so I'm not sure how flexible we can be with diagnostics here.

Or we could just make the macro accept dbg!(5, 10)...
