Raising objects

[Jan Olderdissen]

Carlos,

since object is a type object
(http://www.python.org/doc/current/lib/bltin-type-objects.html) and
not a string, class or instance of a class you can't raise it or
classes derived from it.

That said, I question the point of deriving from object as classes
(and in fact all objects as far as I can tell) are derived from object
as it is. Since object isn't a class, deriving from it probably is
bogus to begin with. What exactly are you trying to do?
