What are advanced monads in Haskell?

Can you explain what advanced monads are in Haskell?

Advanced monads in Haskell extend the basic monad concept, allowing for more complex data handling and control flow.

What are some examples of advanced monads?

Examples include the State Monad, Reader Monad, and Writer Monad, each serving different purposes in functional programming.

How do I implement a State Monad in Haskell?

To implement a State Monad, you define a type that represents a stateful computation, typically using a function type like State s a = s -> (a, s).

Can you provide a simple code example?

Sure! Here's a simple example:

import Control.Monad.State

type Counter = State Int

increment :: Counter Int
increment = do
    n <- get
    put (n + 1)
    return n
