That gives an error:
error: type mismatch;
 found   : List[(Char, List[Int])]
 required: scala.collection.immutable.Nil.type
             input.foldLeft( Nil ) ( (acc, cur) => (cur, flibble(cur)) :: acc )

There is then a market pointing to the :: in the line above. ie. I
think it's saying that it can't figure out how to do:
('a', List(1,2)) :: Nil
