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