Maybe because there's a much better way to write it:

procedure foo();
var
   s1: TStringList = nil;
   s2: TStringList = nil;
   s3: TStringList = nil;
begin
   try
     s1:=TStringList.create;
     s2:=TStringList.create;
     s3:=TStringList.create;
     doWhatever(s1,s2,s3);
   finally
     FreeAndNil(s3);
     FreeAndNil(s2);
     FreeAndNil(s1);
   end;
end;

Best regards,

Nikolay
