Note that generics poison anything they touch. Every language feature need
a generic counterpart, so not only the discriminants need to have
corresponding formal generic parameter, but also the newly added aspect
stuff. I don't know if Ada 2012 has formal generic implicit_dereference.
Does it?
Anyway the first step to do is generic package interfaces. If you want
Vectors, Doubly_Linked_Lists etc to be used in a generic manner they shall
implement an interface (a generic one, because the packages are generic).
Ada lacks means to describe generic interfaces and to match generic
packages against them.
The whole idea of generic containers used for generic programming is not
sustainable, sorry for delivering an inconvenient truth.
If you want generic programming working do it on the class-wide basis.
