Why Go? Use Racket(cxwangyi.wordpress.com)

    package main

    import "fmt"

    func setup_channels(left chan int, num int) chan int {
        for i := 0; i < num; i++ {
            right := make(chan int)
            go func(left, right chan int) { right <- 1 + <-left }(left, right)
            left = right
        }
        return left
    }

    func main() {
        leftmost := make(chan int)
        rightmost := setup_channels(leftmost, 100000)
        leftmost <- 1
        fmt.Println(<-rightmost)
    }

    #lang racket

    (define (setup-channels left idx num)
    (if (>= idx num)
        left
        (let [(right (make-channel))]
        (thread (λ ()
                    (channel-put right (+ 1 (channel-get left)))))
        (setup-channels right (add1 idx) num))))

    (let* [(leftmost (make-channel))
        (rightmost (setup-channels leftmost 0 100000))]
    (channel-put leftmost 1)
    (channel-get rightmost))
