• [ ] Collapse to:
  • [ ] { get; }
  • [ ] { get => <one-line-expression>; }
  • [ ] { get; set; } ?
• [ ] Insert space after get/set
• [ ] Treat hook parameters as function parameters for formatting purposes, e.g. so union types are spaced correctly
• [ ] Don't force line break between attribute and hook
