Można też się uprzeć na:

type
   Int = Integer;
   TPhraseList<Int, T> = class(TObjectDictionary<Int, T>)
   private
     procedure DoParsePacketList(AStrings: TStringList);
   end;

implementation

procedure TPhraseList<Int, T>.DoParsePacketList(AStrings: TStringList);
var
   k: Integer;
   s : string;
begin
   if Assigned(AStrings) then
   begin
     Self.Clear;
     for k := 0 to AStrings.Count -1 do;//linia 212
   end;
end;
