Re: [Haskell-beginners] Couldn't match expected type ‘IO ()’ with actual type [Integer]

@Norbert Melzer - Yeah, I just wanted to provide a solution without shuffling Roelof's code too much, so he'd recognize how is it different from his version. I did write that this is incomplete and requires the list to be reversed later. @Roelof Wobben - Maybe try a different one? There are several popular choices other than LYAH: * FP Complete Shool of Haskellhttps://www.fpcomplete.com/school * Wikibooks: http://en.wikibooks.org/wiki/Haskell * Real World Haskell: http://book.realworldhaskell.org (Warning: while I remember learning from this book some time ago and it was fine, every now and then I see people saying that it's outdated and some examples don't compile) Kind regards, Marcin Mrotek
