While it is not passed explicitly, remember that REQUEST
can almost always be accessed through acquisition:

def __str__(self):
  theRequest=self.REQUEST
  ...
  return theResult

After reading this, I'm not sure I understand what the core
problem is - is it that the REQUEST was not available as an
explicit argument, or am I missing something deeper here?
