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.
