Re: [Haskell-cafe] A good video on monad

Thanks Luke,

A functor is a special kind of one parameter type constructor, that has one of these mapping operations (called "fmap").  It means that they treat their parameter in a particular way, roughly that they do something kind of like returning it rather than depending on it.  Note that you cannot write such a definition for IntFunc2.

This was very helpful. Would you suggest any reading material to get better understanding of theory? Regards, Kashyap
