For example, adding `*` in front of `*expression` is best shown as `**expression` rather than `*(*expression)`. This is not perfect, as it checks whether the operator is already a prefix of the expression, but it is better than it was before. For example, `&`+`&mut x` will get `&&mut x` but `&mut `+`&x` will get `&mut (&x)` as it did before this change.
