Hi, thanks for your mail! I am circulating it to my Haskell teaching colleagues, who are facing the same challenges as Johannes. Am Donnerstag, den 19.11.2015, 21:00 -0430 schrieb Manuel Gómez:
The three classes are distinguished by their expanding APIs, and it’s helpful, if you have enough time for the lesson, to show types that are Functor but not Applicative (e.g. «(,) e»).
There is the instance Monoid a => Applicative ((,) a) Do you touch upon that, or pretend it is not there?
