Where is an example of a monad?
This question already has an answer here:
I wrote this post as an example of using the monad abstraction purely as a practical way to avoid code duplication.
(Many things are Monad s; what makes Monad useful is writing a function once (in terms of Monad ) and then being able to reuse that same function with Future , Option , Either , Writer , State and so on).
