Yes and no. I think an odd streams package would be very useful. (I would certainly find a use for it.) However, I think that it should be possible to get a stream package that neither exhibits the extra forces that the "How to add laziness to a strict language without being odd" paper addresses, nor the missing delays that seem to happen with srfi-40. (No, I have no idea if it is possible, but I see no reason why it shouldn't be .)
