Ooh, this is intriguing! I see a couple of problems, though
it may just be my lack of eddykashun..
1. No conditional or boolean testing would make a lot of
common mathematical functions impossible. (geometry
springs immediately to mind, having to check relative positions
of points and for negativeness.)
2. You specifically stated adding 1, but implied that there
could be no x = x + -1, meaning no negative numbers.
3. Addition and multiplication are easy, but I can't figure out
subtraction or division, not without a conditional, negative
adding, or expressions allowed in the loop statement. Please
give an example!
Thanks
