How about:
package Stack(Interface, Extended_Interface, Completion);
package Stack(Interface) is...
end Stack(Interface);
package Stack(Extended_Interface) is...
end Stack(Extended_Interface);
etc.
(Lots of other good ideas that work well with this approach deleted.)
In the GNAT library model, the one line declaration of the parts
would have to be in a separate file with a new extension, .adp?, but
other than that no problem. Or you could make the part enumeration a
header for the first package part:
parts(Interface, Extended_Interface, Completion);
package Stack(Interface) is...
end Stack(Interface);
Making each part list all of the partitions is the third approach:
package Stack(Interface of Interface, Extended_Interface, Completion) is
end Stack(Interface);
But this could lead to more hassle in maintenance.
