I'd like to showoff some nice Haskell code to a CTO with no experience with FP. I promised to send him a small piece of Haskell so he could get an idea. The code should be easy to read, without obscure looking operators (so sorry, no lens, arrows stuff like that), optionally even do something interesting. Who has the nicest example laying around?
Some ideas: - a wrongly typed piece of code: then show him a) how ghc(i) pinpoints the problem part and is very clear in its demands ("I wanted this, you gave me this") and b) how malleable the type system is. - a declarative graph made with diagrams (with a graphical result displayed) - parsec (even if you go with applicative style, the code is very readable)
