Monad Transformers Hello World

I’ve been searching the webs for a simple example of monad transformers in action in Haskell. Don’t remember if I actually did find one or not, but in any case I’m posting my own Monad Transformers hello world. I really don’t understand why texts explaining Haskell concepts such as these can’t have a simple hello world example to just to see the concept in use in it’s most simple form.
