Yes, but it isn't the default way in C++ to do dynamic instanciation.

I meant :
When you need to instantiate a class, you usually do :
MyClass a;
and not :
MyClass* a = new MyClass();
You're in a value model.
That's my experience as well. However, stack class objects are rare and
to repeat Steven, it comes with the problem of slicing. Only after
learning D that I realized there were two kinds of C++ types in my code:
value types and reference types, latter of which I've achieved with
boost::shared_ptr<C>. So, I think D's separation is the right choice.
However, classes are unnecessarily expensive due to that 'monitor'
member and carry the mistakes of OOP models adopted by Java, C++, and
others. I say this under the influence of open multi-methods[1] and
anemic domain models[2].
