I still don't see, why it works for show but not for my_show.

If I let this be
class My_show a where
my_show :: a -> String
instance My_show Int where
my_show a = show a ++ " :: Int"
instance My_show Integer where
my_show a = show a ++ " :: Integer"
What is the difference to the builtin Show class?
