Just asked, because the following IS possible in Delphi. Either way,
explicit type (as was shown in my second example) is slightly neater
for me as well.

uses
  SysUtils, Classes, Generics.Collections;

procedure WriteSquares(Max: Integer);
var
  List: TList<Integer>;
  I: Integer;
begin
  List := TList<Integer>.Create;
  try
    for I := 0 to Max do
      List.Add(I*I);
....
