Is it possible for template-class to inherit from multiple parents based on parameter pack?

Question

I'd like to achieve something like this:

class C: public Wrapper<C1>, public Wrapper<C2>, public Wrapper<C3> ..... {}

...but pass any number of Cx as variadic template argument to class C:

template<typename... Cx>
class C: // ???????????????

Is it possible? Is there any workaroud for this?

Answer 1

Yes this is possible:

struct A {};
struct B {};

template <typename ...P>
struct C : P... {};

int main() {
    C<A,B> c;
}

or with a wrapper:

template <typename T>
struct Wrapper {};

template <typename ...P>
struct C : Wrapper<P>... {};

Here you can find an example where the same is applied in the context of std::visit .
