Does anybody know why it's not possible to raise Exceptions which are
types (new-style-classes). I know all standard exceptions are classic
classes, but if you make a custom exception which both inherits from a
exception class and a new-style one the it causes a type error when raised.
>>> class b(Exception, object): pass
This might not help you, but have you considered just making
your old-style class *contain a reference* to an instance
of whatever new-style class you want it to contain? Then
the issue goes away.
I can't actually think of a reason to need to base an
exception on a new-style class, but perhaps you have a
good one...
