I loved 'with' while I was learning Delphi/Pascal and hated after the first few months since using it professionaly. I truly believe it warrants/deserves some advice in the documentation, for the beginners. With the code completion in Lazarus there's even less reason to use it - besides any possibly missing compiler optimization...
