Actually, that is not the case. The noexcept property of a destructor
without explicit noexcept annotation is determined by inspecting noexcept
property of destructors of non-static data members of the class and its
base classes. Since these subobjects are private implementation of your
class, and we are not aware of how their destructors are implemented, we
cannot determine whether variant's destructor is noexcept or not. Here's an
static_assert(std::is_nothrow_destructible_v<Variant> == false);
