  63       The display string for Rc, Arc, etc is optional because the expression cannot be evaluated
  64       if the pointee is unsized (i.e. if `ptr.pointer` is a fat pointer).
  65
  66       There are also two versions for the reference count fields, one for sized and one for
  67       dyn pointees.
  68
  69       Rc<[T]> and Arc<[T]> are handled separately altogether so we can actually show
  70       the slice values.
