Subject: graphs in ada (combining two generic units referencing each other)

Hello!

I've some problems programming graphs in ada.
I've declared two generic Units one called simple_node(describing the type
node) and one called simple arc(describing the type arc).
However I need to have type arc to instantiate type node (because of
adjacent lists) and I need to have type node to instantiate type arc (to
define which node the arc is pointing to). But when I want to use both
packages I have to instantiate one first needing the type of the second
generic unit.

Is there any possibility to describe a graph in such a way or do have to
work around keeping nodes and arcs in one generic unit?

Ciao,
Herwig
