Q: exception objects

[Leopold Toetsch]

Pie-thon has Exception objects. We'll need such beasts too. So:
1) How do we "translate" Python classes? Properties only? Or
   full ParrotClass objects?
2) We'll need to classify our exceptions somehow so that we can model an 
exception class hierarchy. We'll also need to catch specific exceptions 
properly so that:

  # from b1.py - pseudo code
  try:
    n = self.P0(n+1)   # recursive
  except RuntimeError:
    # pass
  return n
can catch specific exceptions.
Comments welcome.
