Ah, sweet.

Can somebody with a similar long-time working experience in Haskell 
doctests provide such a list?
It would be helpful in more than one way: It would help advocate 
Haskell, and to the kind of audience that is interested in high quality 
so it's a double win; and it would help other language communities 
improve their doctest ecosystem, and I think that's what most 
multi-language people would very much like to happen.
