The same thing in Haskell: cycle seq = circular where circular = seq ++ circular (or if you want to really golf it) cycle = fix . (++) Ok, to be fair the Scala code is a bit more generic as it works for any abstract sequence, but still, Scala's syntax is awfully heavy compared to Haskell. That's one reason I still prefer Haskell even though Scala is easier to sneak into enterprise projects thanks to JVM. Not to mention that Haskell gives stronger static guarantees and has a more sophisticated type inference system.
