Hi

I have made a generic package called Double_Linked_List. I have also a
package called Wordgroups which has the type Wordgroup and several
functions/procedures connected with the type.

Now I want to have a List of Wordgroups. 

First I made a child package Wordgroups.List of the Wordgroups pacakge
like this:

with Double_Linked_List;
with Wordgroups;

   package Wordgroups.List is
         new Double_Linked_List (Data_Type => Wordgroups.Wordgroup_Type);


Now I relized that it would be nice to have a procedure like:

   procedure Add (List        : in out  List_Type;
                  Word        : in      String;
                  Explanation : in      String) is

      Wordgroup : Wordgroup_Type;

   begin
      Create (Wordgroup, Word, Explanation);
      Append_Element (List, Wordgroup);
   end Add;

so that I don't have to do:

   Create (Wordgroup, Word, Explanation);
   Append_Element (List, Wordgroup);

in the rest of the program, only Add.

But I cannot add this to Wordgroups.List.

I would appreciate some hints on how to do something like this. Thanks
in advance.
