I never really understood why it was thought to be relevant, but I was challenged to show that n+k patterns occurred in Hackage.

Why is it relevant?

Some people think that the popularity of a feature in an openly accessible collection of Haskell sources is relevant to whether it should continue to be supported, in a way that, say, appearance in textbooks, utility to beginners, and contribution to readability are not. Apparently. I don't understand this. n+k patterns are the ONLY Haskell98 feature scheduled for removal from Haskell'.
