The Evolution of a Haskell Programmer

I found this link about The Evolution of a Haskell Programmer quite interesting. It shows a bunch of different approaches to write the well known factorial function in different ways using Haskell. It ranges from the simple pattern-oriented implementation, to confusing implementations with more than 30 lines of Haskell code. And always, always with a brilliant sense of humor.

Let me show you a little of that article:

Senior Haskell programmer

(voted for   Nixon   Buchanan   Bush -- "leans right")

fac n = foldr (*) 1 [1..n]

 

Another senior Haskell programmer

(voted for   McGovern   Biafra   Nader -- "leans left")

fac n = foldl (*) 1 [1..n]

Brilliant ;)
