Thanks Kim for your answer but as far as I understand strict evaluation should save in space as expression is not expanded in terms of thunks,but I can't understand time savings.Can you pls explain strict evaluation?
For this particular problem, start here: https://en.wikipedia.org/wiki/Memory_hierarchy What happens to original program that has a sprawling mass of thunks all over RAM? The CPU spends most of its time waiting on the memory bus. And that's not even going into things like disk-backed virtual mem. -- Kim-Ee
