經(jīng)過(guò)1個(gè)小時(shí)的奮斗，修了3個(gè)bug，終于使得Kernel FP能運(yùn)行的代碼漸漸多了起來(lái)。現(xiàn)在可以看看純函數(shù)式語(yǔ)言簡(jiǎn)潔的代碼及運(yùn)行結(jié)果啦！
下面是很多用于測(cè)試的main函數(shù)：
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!"
通過(guò)類(lèi)型推導(dǎo)、模板實(shí)例化和運(yùn)行時(shí)assembly的生成之后，就可以得到運(yùn)行結(jié)果了：
