  3 trizip :: [a] -> [b] -> [c] -> [(a,b,c)]
  4 trizip a b c
  5         | null a = []
  6         | null b = []
  7         | null c = []
  8 trizip (x:xs) (y:ys) (z:zs) = (++) [(x,y,z)] (trizip xs ys zs)

 10 main = do
 11         let asciit =  trizip [0x1..0x7f] ['\x01'..'\x7f'] [0x1..0x7f]
 12         print "Done!"

　　

运行方式

daniel@daniel-mint ~/haskell $ ghc --make trizip.hs -o trizip
[1 of 1] Compiling Main             ( trizip.hs, trizip.o )
Linking trizip ...
daniel@daniel-mint ~/haskell $ ./trizip
"Done!"
daniel@daniel-mint ~/haskell $

　　

或者

daniel@daniel-mint ~/haskell $ runhaskell trizip.hs
"Done!"
