[Adopted as a DR at the November, 2019 meeting.]

Consider an example like the following:

  typedef const int CI[3];
  constexpr CI &ci = CI{11, 22, 33};
  static_assert(ci[1] == 22, "");

This is ill-formed because the lifetime of the array temporary did not start within the current evaluation. Perhaps we should treat all lifetime-extended temporaries of const-qualified literal type that are initialized by constant expressions as if they are constexpr objects?
