Re: [Haskell-cafe] Reversing a string of words: C# v Perl V Ruby vHaskell

Finally, and please don't laugh, in Haskell (GHC):

reverseWords :: String -> String reverseWords xs = (concat (intersperse " " (reverse (words xs))))

which does appear to work correctly. However, I would like to do justice to Haskell as a language -- and given that my clumsy Haskell is not written in expert style -- I'm hoping that someone on this list might offer a better, faster, or more idiomatic Haskell solution to this little problem.

What about just: reverseWords = concat . intersperse " " . reverse . words -- http://www.metamilk.com
