Martin Albrecht requested this functionality for his code, and it would also simplify mine. For short linear programs, of when some global variables do not require the creation of a new dictionary of variables ( from which only one field would be used ), this trick is good enough !

  • try: foo except AttributeError: seems to be favoured in the Python community over hasattr. It is also faster if the attribute does in fact exist.
  • Why do you call __getitem__() instead of using the normal syntax [x]?
