846: WIP: Enable parsing of attributes inside a match block r=matklad a=vipentti We allow invalid inner attributes to be parsed, e.g. inner attributes that are not directly after the opening brace of the match block. Instead we run validation on `MatchArmList` to allow better reporting of errors. This fixes #845 and works towards #759 Co-authored-by: Ville Penttinen <villem.penttinen@gmail.com>
