A weak-reference object. You construct a weak reference by passing
any COM object you like. If the object does not support weak
refs, you will get a standard NS_NOINTERFACE exception.
Once you have a weak-reference, you can "call" the object to get
back a strong reference. Eg:
>>> some_ob = components.classes['...']
>>> weak_ref = WeakReference(some_ob)
>>> new_ob = weak_ref() # new_ob is effectively "some_ob" at this point
>>> # EXCEPT: new_ob may be None of some_ob has already died - a
>>> # weak reference does not keep the object alive (that is the point)
You should never hold onto this resulting strong object for a long time,
or else you defeat the purpose of the weak-reference.
