We could store the hasWeakRef bit in the operation and just have it always call a context level facility to invalidate on destruct if the bit is set. There is space to stash a bit in the operation, just not a pointer. 

Advantage to that would be that it wouldn't require atomics or other things that interact badly with threading.
