How to access a private field from a class helper in Delphi 10.1 Berlin?

Question

I would like to use Gabriel Corneanu\'s jpegex, a class helper for jpeg.TJPEGImage. Reading this and this I\'ve learned that beyond Delphi Seattle you cannot access private

Answer 1

Today I found a neat way around this bug using the with statement.

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

Besides that Embarcadero did a nice job building walls to protect the private parts and that's probably why they named it 10.1 Berlin.
