Can you give me an example of how to use a Monad Transformer?

Sure! For instance, you can use the MaybeT transformer to combine the Maybe monad with another monad, like IO, to handle computations that might fail.

How do I install the necessary libraries for Monad Transformers?

You can install the transformers package using Cabal or Stack. Just add transformers to your project's dependencies.

What are some common Monad Transformers I should know about?
