Replacing the Prelude module using Backpack

https://typeclasses.com/no-prelude

This project demonstrates one of the many ways to avoid using the default Prelude module. We use Cabal's mixins feature (also known as Backpack) to specify that we want to:

1. Ignore the Prelude module from the base package; and
2. Instead use a different module from another package (in this example, that's the Foundation module from the foundation package) aliased as Prelude.
