Question

Is it possible to pass an arbitrary number of template template classes to a class? Something like this:

template < template < typename > ... class types > struct T {};

When that’s done, I’d like to inherit from them, like this:

template < typename p, template < typename > ... class types >
struct T : types <p> ... {};

How would I get that behaviour?

It looks like you’ve just misplaced the ellipsis, try this:

template < template < typename > class... types > struct T {};

Or to inherit from them:

template < typename p, template < typename > class... types >
struct T : types <p>... {};
