Hi,

Consider <http://www.adaic.org/standards/95aarm/html/AA-3-9-2.html>, 
example from 20.c to 20.f.

It is said that the following call:

P2.Op_B(Arg => X);

is non-dispatching.

My confusion is that Op_B is private in P2. X is declared in P2 as well. 
In the above call, I'd expect P2.Op_B to be called (which is actually 
the case), but since everything is known statically, then I'd expect as 
well to get compile-time error due to the fact that P2.Op_B is private.

In other words: how can I get compile error when calling private P2.Op_B?
If it's not possible, what's the point in making it private?
