Please don't take this as in invitation to disregard the excellent
advice already received in this thread - I just want to point out that
python can usually be bent to your will.  Observe:

  
  from withhacks import namespace

  with namespace(class1):
      attr1 = 1
      attr2 = 2


This will do pretty much what you get from the "with" statement in
javascript (I assume it's similar to Visual Foxpro).


But don't use this in any real code.  Seriously, don't even think about
it.  You don't want to know the kind of abuses that go on under the
covers to make this kind of syntax hacking work...



  Cheers,

     Ryan
