removed constexpr from exception policies. this eliminates obstacle to gcc compilation which doesn't support constexpr throw unfortunately, all versions of gcc trip compiler fault so gcc not supported for now safe_literal - make this an unsafe type since it doesn't have policies - this might change in the future
