You're right but the with statment in Pascal/Delphi is 
deprecated. While it was usefull in a simple branch, it was 
error-prone. In "D" the scope() statement can be used to overcome 
the old Pascal pattern: with whatIcreate try finally free.

quote from Delphi XE4 release (technical pdf):
"4. OTHER LANGUAGE CHANGES
Besides string type changes and objects memory management, there 
are other current or
expected changes in the new Delphi ARM compiler that you can 
easily start to adopt:
  Sooner or later, the with statement is going to be deprecated 
and removed from the
Delphi language. You can easily start removing it now from your 
code, and most Delphi
developer will agree this is a good idea anyway, given some of 
the hidden pitfalls of this
keyword.
