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...
