I this supposed to work too?

//  This is going to be a variadic array.
#include <cstddef>
#include <type_traits>

template<typename T, std::size_t Dim, std::size_t... Dims>
  struct tensor
  {
  public:
    typedef std::conditional<sizeof...(Dims) == 0, T, tensor<T, Dims...>>
_Elem;
    _Elem elem[Dim]; // (Dim == 0 ? 1 : Dim) like array?
  };
