It seems that you don't understand me: I need different boolean functions
for different derived tagged types. If we specify Type_Invariant or
Type_Invariant'Class this is the same function because it can be specified
only for the base class not my derived classes.
Or maybe I do not understand you? If so, please explain.
Hm, well, Type_Invariant'Class may point to dispatching function which can
be overridden in the derived classes. Isn't it what you mean?
