I forgot to mention that even Haskell has had some strangeness in its pattern matching once, that it banned later, as recently as 2010. https://stackoverflow.com/questions/3748592/what-are-nk-patt... > What do they mean by "n+k patterns"? I guess it's the second line, but I don't get what might be wrong with it. Could anyone explain what is the issue there? Why aren't these n + k patterns allowed any more in Haskell 2010? |
