That is true, it is possible, but I don't think it fits very well in

I don't think this is quite true. though it might be a useful simplification. Obviously it is true for volatile registers, but I believe the funclet receives a CONTEXT with the nonvolatiles restored. Obviously cumbersome to access, but it lets you enregister
