How to access private methods without helpers?

Question

In Delphi 10 Seattle I could use the following code to work around overly strict visibility restrictions.

How do I get access to private variables?

Answer 1

If you want a clean way that does not impact performance, you still can access private fields from a record helper using the with statement.

function TValueHelper.GetAsInteger: Integer;
begin
  with Self do begin
    Result := FData.FAsSLong;
  end;
end;

I hope they keep this method open, because we have code with high performance demands.
