Why hack them with scoped? The need exists, since you provide a 
hack for it.

Reference classes in C++ are polymorphic & reference, but their 
destructor/disposer gets called.

There is a delete that triggers that or a smart pointer. I don't 
care if the delete or the destructor really frees the memory, but 
I would like it to get called, to release other resources that 
the object might have locked and to mark the object as "invalid". 
Later access to it shall triger an exception: "invalidObject".

Call it dispose if you like, because delete is too much like 
freeing memory.

Is there an intermediate type between structs and classes?
