Scala: Bringing a Type's Value to Life with Just One Inhabitant

It can be difficult to work with type-level computations in Scala, particularly when working with structures such as singleton types. Trying to extract values from types that presumably have a unique resident presents a challenge. We can optimize these calculations by utilizing Scala 3's inline methods and Shapeless' Witness. This method is a useful tool for Scala developers since it is necessary for metaprogramming, compile-time optimization, and improved type safety.
