Suppose I have a Thingy:

myThingy = Thingy()

I want to give you some amount of access to manipulate myThingy, so I make a Referenceable which has some connection to it:

myReferenceable.thingy = weakref.proxy(myThingy)

and I send you the Referenceable. Now suppose I do

del myThingy

Now myThingy will be garbage collected. Then, if you invoke methods on myReferenceable, they'll fail. Is this what we want, or should I tell you that your RemoteReference should be considered stale?

If I'm not thinking about this correctly please advise. I realize that I could have done

myReferenceable.thingy = myThingy

so that myThingy lives as long as myReferenceable, but this doesn't actually seem like what I would normally want.
