There is a limitation of the current system in that the out contract
can't see the scope of the in contract. Walter and I tried to find a
solution, but it was technically difficult in the presence of inheritance.
C#4 designers seem to have found a way to implement "old" (Prestate Values)
correctly enough, so can't D2 adopt a similar solution?

I don't think they have contracts in interfaces, which is where most
difficulty lies. At any rate, it's not that we can't do it, it was just
a large effort that we decided to postpone.
Is there anything wrong with the workaround I suggested?
