So, you are saying that

class foo { };

is not a class in C++?

No, I meant C++ does not have a notation for Ada's concept of a class.
(You may turn it the other way around and say C++ does not have a
notation for a pointer to a specific type.)

I stand corrected.  The last time I wrote any C++ was back in 2001 :)
