Maybe you need to implement interfaces to make a class a generic
container...
But the items you put inside that container do not have to implement an
interface.

This for example works:

class method ConsoleApp.Main;
Var
FTestList: List<Integer>;
TempInt: Integer;
begin
FTestList := new List<Integer>; //<-- creates a strongtyped Integer
container
FTestList.add(3);
FTestList.add(8);
TempInt := FTestList.Item[0] + FTestList.Item[1];
Console.WriteLine(TempInt.ToString); //<-- prints 11
Console.ReadLine;
end;
