According to this http://zvon.org/other/haskell/Outputprelude/elem_f.html elem is Eq a => a -> [a] -> Bool but according to my ghci :t it's this elem :: (Foldable t, Eq a) => a -> t a -> Bool I understand the first, but not the second, especially with the t. What is this saying extra, different from the first one? ⨽ Lawrence Bottorff Grand Marais, MN, USA borgauf@gmail.com
