New submission from Richard Oudkerk <shibturn@gmail.com>: In the documentation on weakrefs there is the following quote Note: Weak references to an object are cleared before the object’s __del__() is called, to ensure that the weak reference callback (if any) finds the object still alive. But I think the weakref is always dead by the time the callback is invoked. The first paragraph from the documentation for weakref.ref(object[, callback]) contains the following: If callback is provided and not None, and the returned weakref object is still alive, the callback will be called when the object is about to be finalized; the weak reference object will be passed as the only parameter to the callback; **the referent will no longer be available**. Which does prompt a question: what use is there for the weakref argument to the callback if it already dead?
