[Chicken-users] nested loop over lists

[Jinsong Liang]

Hi,

I want to do nested loops over three lists like the following pseudo code:

for i in '(1 2 3)

    for j in '(4 5 6)

        for k in '(7 8 9)

          //do calculation using i, j, and k. The three lists are not related.

        end

    end

end

What is the best way to do this in Chicken? I can use (for-each ...) or (do ...) but it seems neither is straightforward.

Thank you!
