It is always difficult to save a repository of code snippets that you consider useful. Sure, you could keep them in a blog or post them on some random wiki. These both work, but in my case, I will be hosting a Haskell cookbook including useful Haskell full source and snippets. It may include the "wrong" way to do things in Haskell and the "right" way but I will let you decide. And all examples will compile with a modern Haskell (GHC is the target system).
