I think it's also because C++ has no generic concept of "zero"; otherwise one could have defined the first element of adjacent_difference(v) as v(1)- zero<typeof(v)>, and it would have been type-stable.

For anyone wanting to go deeper, Knuth's Concrete Mathematics covers the discrete calculus topics mentioned here (and much more).
