The JSON-specific branch uses a hack comment referencing an undefined parenthesizerRule. Consider refactoring this block to either integrate a proper parenthesizing solution for JSON files or add a more descriptive comment on why the current approach is necessary.

Fixes #660
I'm not happy with the emit change, but I don't know what the right fix is. Strada did parenthesizing completely differently.
