More than that even. I think we should have, at some point, something like:

• a function which, given an HirId checks whether inserting something in place of this node might need to be parenthesized (even better if it returns an associativity level)
• a function which, given a suggestion, checks whether it might need to get parentheses (even better if it returns an associativity level)
• a function which, given an HirId and a suggestion, returns an updated suggestion with added parentheses if this is necessary
