[Zope-CMF] ObjectMoved exception

[Kevin Carlson]

Can anyone explain the third argument to the __init__ function of the
ObjectMoved exception class that is defined in
Products/DCWorkflow/WorkflowCore.py?  Here is the code:

class ObjectMoved (Exception):
    '''
    Raised to tell the workflow tool that the object has moved.
    Swallowed by the workflow tool.
    '''
    def __init__(self, new_ob, result=None):
        self._ob = new_ob  # Includes acquisition wrappers.
        self._r = result

    def getResult(self):
        return self._r

    def getNewObject(self):
        return self._ob

It appears that this is a result code of some sort, but I have no idea what
is expected...
