Ups, you are right... but the error is still the same
      in-class initializer for static data member is not a constant expression
	      static const int value = ((const typename std::decay<T>::type*)(nullptr))->size();
		                           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
