经过1个小时的奋斗，修了3个bug，终于使得Kernel FP能运行的代码渐渐多了起来。现在可以看看纯函数式语言简洁的代码及运行结果啦！
下面是很多用于测试的main函数：
1 module startup
2 import list
3
4 def main0 = length "vczh"
5 def main1 = head "vczh"
6 def main2 = tail "vczh"
7 def main3 = concat "genius" " vczh!"
8 def main4 = isempty ""
9 def main5 = isempty "vczh"
10 def main6 = transform (iadd 1) (list 1 (list 2 (list 3 empty)))
11 def main7 = reverse "abcde"
12 def main8 = intersperse '|' "vczh"
13 def main9 = flatten (list "vczh" (list " library" (list " ++" empty)))
14 def main10 = pairlist "genius" "vczh"
15 def main11 = fold 0 iadd (list 1 (list 2 (list 3 empty)))
16 def main12 = all (iequ 0) (list 0 (list 1 (list 2 empty)))
17 def main13 = any (iequ 0) (list 0 (list 1 (list 2 empty)))
18 def main14 = take 5 (iterate (iadd 1) 0)
19 def main15 = take 5 (repeat 99)
20 def main16 = take 5 (cycle (list 1 (list 2 empty)))
21 def main17 = drop 5 "genius vczh!"
通过类型推导、模板实例化和运行时assembly的生成之后，就可以得到运行结果了：
1 CTOR : system.empty=0,0
2 CTOR : system.false=1,0
3 CTOR : system.list=2,2
4 CTOR : system.true=3,0
5 CTOR : sysutils.pair=4,2
