for/fold to accumulator assigments
Modified for/fold (no generic input streams: explicit index sequence).
((a1 a2) (for/fold
((i (in-range 0 n)))
(values (+ (arr i) s1)
(* (arr i) s2)))))
Question is: how to make this easier in C? The above is still an
expression language, while C is an assignment language..
So let's keep the above form, since it keeps us in the expression
domain, and it also makes C code simpler, since we can juse use
_ a1 = s1;
_ a2 = s2;
The modified for/fold form then can be
(fold-dim i n
However, that one is not a map/fold as the one we're abstracting, so
maybe stick to the current approach first, then move to an "abstract"
accumulator later (for/fold style).
