Towards literal O[U]String types in C++20
...(where destructors can be constexpr), making
21584b304b21bfe6b99b6f29018c6b754ea28fc0 "make OUString(OUStringLiteral)
constructor constexpr" and 983c1146ac80c038feae653e8e3752a72171d6cb "actually
make OString(OStringLiteral) constructor constexpr" actually useful and
eventually removing the need for O[U]StringConstExpr again
