// but it was not removed by a mistake.
//
// So, we need to find a place where to stick validation for attributes in match clauses.
// Code before refactor:
// InvalidMatchInnerAttr => {
//    write!(f, "Inner attributes are only allowed directly after the opening brace of the match expression")
// }
