Hello,

I would like to know if there are standard solutions for those 2 things in
Ada95 :

1) Introspection

2) The equivalence of what is done in Java by :
class MVFramework

        class Model extends Object {...}
        class View extends Object {...}
}
class MVSpreadsheetFramework extends MVFramework

        class Model {...} // Overrides class MVFramework.Model
        class View {...}
}

.i.e. overriding a nested class
