Sorry, something went wrong.

I am not sure if this is actually better than std::is_same_v<T, NonTriviallyDefaultConstructible> || std::is_same_v<T, NonTrivial>, we can do the comparison here not because the underlying is a scalar or an aggregate, it is because we know it has a well defined value-initialization.
