(_Optional_base(in_place_t, initializer_list<_Up>, _Args&&...)): Turn the int-pack constraint hack into a saner bool. (_Optional_base<_Tp, false>::_Optional_base(in_place_t, _Args&&...)): Constrain. (_Optional_base<_Tp, false>::_Optional_base(in_place_t, initializer_list<_Up>, _Args&&...)): Turn the int-pack constraint hack into a saner bool. (optional(_Up&&)): Constrain against in_place_t. (optional(in_place_t, _Args&&...)): Constrain. (constexpr optional(in_place_t, initializer_list<_Up>, _Args&&...)): Turn the int-pack constraint hack into a saner bool. * testsuite/20_util/optional/cons/value_neg.cc: Add a test for a type that is constructible from in_place.
